What is ventricular fibrillation: Definition and explanation!

Problems with the heart rhythm are becoming more common and can lead to real problems. Especially when the heart goes into ventricular fibrillation. In the worst case, this can lead to a quick death. But what exactly is ventricular fibrillation? And what can you do about it? Here’s the answer!


Ventricular fibrillation is the most dangerous type of cardiac arrhythmia. Cardiac arrhythmias are not unusual and can happen to people at any time. There are different Causes for this.   

When cardiac arrhythmias occur, the person affected feels unwell and experiences various Symptoms. Cardiac arrhythmias can occur to varying degrees. Normally, the human heart beats about 60 to 90 times per minute. But there are also differences between gender and age. In women, the heart usually beats a little faster than in men.   

The following differences occur with a resting heart rate (beats/minute): 

  • Babies: between 120 and 140  
  • Infants: between 100 and 120   
  • Adolescents: between 80 and 100  
  • Adults: between 60 and 80   

For seniors, the resting pulse can also be somewhat higher than 60 to 80. While in an adult the heart beats between 60 and 80 times per minute, in ventricular fibrillation the value is much higher. The value is around 300 heartbeats per minute, which is so high that the heart can no longer pump blood. As a result, no more blood enters the bloodstream and cardiovascular arrest occurs.   

Difference compared to atrial fibrillation  

People often confuse ventricular fibrillation with atrial fibrillation. Although it sounds very similar, it is actually not the same. In ventricular fibrillation, the heart is no longer able to pump blood into the bloodstream. This causes the heart to stop and resuscitation measures have to be taken immediately.   

In atrial fibrillation, on the other hand, there is no direct cardiac arrest. Instead, atrial fibrillation can lead to further damage to the body. Basically, atrial fibrillation causes blood clots, which can then lead to further heart disease or even a stroke.   

Thus, the chance of survival is much lower with ventricular fibrillation than with atrial fibrillation. In any case, those affected are dependent on first aid. However, the procedure for atrial fibrillation is different from that for ventricular fibrillation. Learn more about First aid instructions for ventricular fibrillation.

Root causes 

The possible causes of ventricular fibrillation can be very different. The most common cause of ventricular fibrillation is heart disease. But there are still cases where the cause cannot really be determined. Or where a pre-existing condition has not yet been detected. So even people who make a healthy impression can suddenly be affected by ventricular fibrillation.   

The most common causes are:  

  • Heart attack  
  • Heart failure 
  • Heart defects  
  • Coronary heart disease   
  • Congenital heart defects  
  • Medication  
  • Anaesthetics  
  • Gastric deficiency  
  • Potassium deficiency 


The symptoms of ventricular fibrillation are relatively clear and recognisable. The symptoms are also different from those of atrial fibrillation. In atrial fibrillation, victims are conscious and complain of other symptoms, such as chest pain or shortness of breath.   

In ventricular fibrillation, on the other hand, the victim suddenly faints. Before this happens, the affected person usually gives a sigh or a slight groan. The victim then lies unconscious and unresponsive on the floor. Breathing then stops and a pulse can no longer be detected. If this is the case, first aid must be given immediately. Otherwise, ventricular fibrillation will lead to the rapid death of the person affected.  

What to do in case of ventricular fibrillation?  

If ventricular fibrillation occurs, you should immediately start cardiopulmonary resuscitation. Detailed instructions for cardiopulmonary resuscitation can be found right here.   
In addition to resuscitation measures, the use of a defibrillator can also be helpful. If such a device is available nearby, you should not be afraid to use it. A comprehensive explanation is usually available at the location of the defibrillator. In addition, many buildings and facilities are now equipped with a defibrillator. Staff at places such as airports or railway stations are also usually trained in the use of the devices.   

In addition to fast first aid, ventricular fibrillation also requires fast and professional medical help. With an emergency app, such as the TarisApp, medically trained passers-by in the immediate proximity can be quickly asked for help. This means that even in the case of ventricular fibrillation, a trained doctor or a trained first aider in the immediate vicinity can help quickly.   

Did you know? 
After dialling the emergency number, it can take up to 15 minutes on average for the emergency services to arrive 

Preventing ventricular fibrillation 

Ventricular fibrillation can be prevented by regular check-ups with a doctor or by eating a healthy, balanced diet. Preventive medical examinations can, for example, diagnose pre-existing heart conditions that could trigger ventricular fibrillation. By diagnosing and then treating the pre-existing heart condition, the risk of ventricular fibrillation can be minimised.   

A healthy and balanced diet is very important, especially for the quality of life and the body. It is especially important for minimising the risk of heart disease. A healthy and balanced diet can also be supported by regular exercise. Sporting activities can strengthen the body and protect against pre-diseases.  

The risk of ventricular fibrillation automatically increases with age. For this reason, older people should always check their blood pressure themselves. This can be done with a blood pressure monitor, for example. If the values are abnormal, a doctor can be consulted.

Recognising stroke: How can I recognise it?

Every year, more than 15,000 people in Switzerland suffer a stroke. Next to heart attacks, strokes are one of the most common causes of death. The chance of survival increases by reacting quickly. But how can you recognise a stroke? We provide the answers.

How do I recognise a stroke?

Two important factors play a role in recognising a stroke. The first is the appearance of the symptoms. Here it is important to know the general symptoms of a stroke. Secondly, you should familiarise yourself with the FAST test. With the help of this test, you can quickly and easily recognise whether someone is currently suffering a stroke.


The cause of a stroke is usually either a cerebral haemorrhage or a vascular occlusion (cerebral infarction). In the case of a cerebral haemorrhage, the blood reaches our brain; in the case of a vascular occlusion, too little oxygen reaches the brain. These are two different causes of a stroke, yet the symptoms are very similar in both variants.
Symptoms of a stroke include:

  • Nausea
  • Headache
  • Stiff neck
  • Paralysis of the face, leg and arms
  • Drooping corners of the mouth
  • Closed eyelid
  • Speech problems
  • Vision problems

Since the left side of the brain is responsible for the right side of the body and vice versa, it is easy to find out which region of the brain is affected. For example, if paralysis occurs on the right side of the body, it can be diagnosed that the stroke is taking place in the left brain region. This is enormously important, especially for first aid and for the doctor treating the patient. In order to detect a stroke even more quickly and accurately, a FAST test can be carried out.

FAST test

A FAST test is a simple test that can be used on anyone. You ask the person, you think is having a stroke, questions. Depending on how the person reacts or what answers they give, you can quickly recognise or rule out a stroke. But what does FAST actually stand for? The term comes from the English and stands for Face, Arms, Speech, Time.

To use a FAST test successfully, you should proceed as follows:

  • Face: First you should ask the person to smile. If the affected person has difficulty doing this or one corner of the mouth hangs down, it indicates hemiplegia.
  • Arms: The next step is to ask the person to stretch their arms forward. The palms should point upwards. If the person does not manage to do this, you can assume that they have paralysis. This is because in paralysis you cannot raise your arms, instead one arm starts to sink.
  • Speech: Ask the person something and have the person speak a simple sentence. If the person has difficulty doing this, it indicates a speech disorder.
  • Time: Every minute counts! Dial the emergency number immediately and provide first aid if necessary. The faster an emergency doctor arrives, the higher the chances of survival or the lower the consequential damage.

Note: You can also request first aid in an emergency with our Taris App. You can find out more about this right here.

Types of stroke

In the case of a stroke, the symptoms can either appear clearly or they are not even noticeable. A distinction is made between a normal stroke and a silent stroke.

Silent stroke

This is a mild or gradual stroke. Silent strokes are hardly noticeable and are very difficult to recognise. As a rule, the symptoms only occur temporarily, for example during sleep. When the affected person wakes up the next morning, they usually no longer feel the symptoms.
Only with time do small abnormalities, such as memory problems or disturbances in walking, become noticeable. This is because the cause of the stroke occurs in regions of the brain, although the damage is not severe. A silent stroke is usually only recognised when a person accidentally undergoes a CT or MRI scan. This is when the permanent infarct scars become noticeable. Now the question arises, how bad is such a silent stroke?
Since the symptoms here are only very weak, they are initially only a higher risk of suffering a normal stroke. In other words, several silent strokes could be a sign of a more severe stroke. In addition, the risk of dementia increases because the brain region is affected.

Risk factors stroke

Most strokes can be avoided and thus also prevented. The most important thing is a healthy lifestyle. An unhealthy lifestyle increases the risk of suffering a stroke. In addition, the probability of suffering a stroke increases with age. But this can also be avoided. In old age, you should therefore have regular check-ups with a doctor. This way you can prevent a stroke.
The most important factors are:

  • Healthy and balanced diet
  • Sufficient exercise
  • Abstain from alcohol and smoking.
  • Avoidance of overweight
  • Pre-existing conditions

Especially if you have a pre-existing condition, you should consult your doctor. Pre-existing conditions can increase the risk of a stroke. Pre-existing conditions such as diabetes, arteriosclerosis, dyslipidemia or obesity can be problematic. Arteriosclerosis, for example, causes a blockage of blood vessels, which can be the cause of a vascular occlusion. And a vascular occlusion (cerebral infarction) in turn is one of the two possible causes of a stroke. It is also the most common cause of stroke.

Stroke: This is what happens in your body!

In old age, a stroke is one of the most common diseases. But what exactly is a stroke and how does it manifest itself? We got to the bottom of the questions.

What is a stroke?

A stroke is a disease related to the brain. It affects parts of the brain where the oxygen supply is interrupted. In other words, the brain is no longer supplied with sufficient oxygen and slowly dies. Therefore, in the event of a stroke, one must act very quickly and take first aid measures.
The lack of oxygen supply to the brain usually occurs when a blood vessel becomes blocked. This means that not enough oxygen can reach the brain. Another cause could be a brain haemorrhage. In this case, blood flows into parts of the brain where the blood should not actually flow through.
Different symptoms can then occur with a stroke. This is because different symptoms occur depending on the region of the brain that is affected. This is because the left side of the brain is responsible for the right side of the body and the right side of the brain is responsible for the left side of the body. This explains why hemiplegia occurs on the right or left side of the body after a stroke.

What happens during a stroke?

If the cause of the stroke is a blocked vessel, it is generally referred to as a cerebral infarction. A clogged blood vessel is caused, for example, by pre-existing conditions such as arteriosclerosis. This pre-existing disease usually occurs at an older age because the blood vessels have deposits. But a bad lifestyle with poor nutrition and little exercise can also trigger constrictions in the blood vessels.
If a blood vessel is finally blocked, not enough blood and thus oxygen can reach the brain. But since our brain can only survive with a sufficient supply of oxygen, it slowly dies. But in order to continue living, we need a functioning brain. As soon as the brain starts to die, it tries to send signals. This is when the symptoms appear. Depending on the severity, the symptoms are weaker or stronger.
If a blood vessel bursts, this is called a cerebral haemorrhage. Blood reaches areas of the brain through the burst blood vessel. Here, too, a previous illness is usually the cause of the burst vessel. In addition to cerebral haemorrhage, in rare cases there is also bleeding of the spaces between the brain and the meninges. This is where the cerebrospinal fluid is located.

What are symptoms of a stroke?

Different symptoms can occur with a stroke. It depends on the severity and the region of the brain affected. Nevertheless, there are also clear and typical symptoms of a stroke.
These include:

  • Stiff neck
  • Nausea
  • Severe headache
  • Various paralyses (arms, legs and face)
  • Drooping corners of the mouth
  • Eyelid closed on one side.
  • Speech disorders
  • Impaired visual functions

There are often cases in which a stroke only becomes noticeable gradually or the person affected does not notice it themselves. If the person behaves in a conspicuously strange way, it is very easy to carry out a so-called FAST test.

  • F = Face
  • A = Arms
  • S = Speech
  • T = Time

This test can be used to see if a person is possibly having a stroke. You should look for drooping corners of the mouth (F), paralysis of the arms (A) and speech functions (S). To do this, just have the person smile, raise their arms and speak. If the affected person encounters difficulties in doing this, dial the emergency number as soon as possible (T).

What are the causes of a stroke?

The main causes leading to a stroke are either a blocked or a burst vessel. As a result, not enough oxygen reaches the brain, or a brain haemorrhage occurs. But how does it get that far in the first place?
Again, other causes are the reason for this:

  • Pre-existing conditions such as arteriosclerosis
  • Poor diet
  • Not enough exercise
  • Smoking
  • and much more.

But age also plays a role in a stroke. It is not unlikely that you will suffer a stroke at an advanced age. Sometimes you get off quite well and the consequences are not serious. The crucial thing is to act quickly and get the right treatment. In many cases, however, the consequences are severe, such as paralysis. Here, the subsequent treatment by a specialist is of great importance. You are often very limited, but you can go on living.

Consequences of a stroke

As with the symptoms, the consequences of a stroke vary depending on the severity. Some effects are more severe and others are less severe.
Nevertheless, there are typical consequences after a stroke:

  • Speech disorders
  • Reading and writing disability
  • Difficulty swallowing
  • Difficulty chewing
  • Long-term paralysis of certain regions (arms, legs, etc.)
  • Long-term hemiplegia

If these consequences occur, one should undergo treatment by a doctor. Here, the doctor determines the appropriate treatment individually for the problems of the affected person. This includes, for example, therapy sessions with a physiotherapist to stimulate the impaired body functions again. But it does not always work.

Prevent stroke

Preventing a stroke is of course very difficult. In principle, you have to make sure that a vascular occlusion or cerebral haemorrhage does not occur. For this to happen, the blood vessels must continue to function well. The prerequisites for this are a balanced diet and sufficient exercise.
With these two measures, you can counteract the causes of a stroke enormously. It is enough to go jogging or for a walk on a regular basis. Of course, these measures must be adapted to your age. In addition, you should stop smoking or, if necessary, alcohol consumption now at the latest. These factors can also damage the blood vessels in the long run.

Heart failure: What you need to know about heart disease!

When people talk about heart failure, they often associate it with a heart attack. But when do we speak of heart failure and when of a heart attack? What are the differences and perhaps also the similarities? We will enlighten you!

What is heart failure?

According to the definition, heart failure is a weakness of the heart. Due to cardiac insufficiency, the heart is no longer able to pump enough blood into the body. As a result, our organs and muscles are no longer supplied with enough oxygen. This in turn affects our organs and muscles. In short, this is a heart disease with a pumping disorder.
Nevertheless, it can already be a case of heart failure if the heart can no longer relax and expand properly. This is also referred to as heart failure. This type of heart failure usually occurs in combination with high blood pressure, heart muscle inflammation or heart attack. After these diseases, the heart is usually so weakened that heart failure can occur as a result.

What happens in heart failure?

According to the definition, heart failure is a weakness of the heart that prevents the heart from performing at 100% of its usual capacity. There are many different ways in which a heart can be limited in its functions. As a rule, the heart can no longer count on its full pumping capacity. In other words, the heart can no longer work as well and you are limited in certain situations. But how does heart failure happen in the first place? There are various causes for this.


Basically, heart failure occurs at an advanced age because the heart automatically loses power over time. In other words, it is a natural course that one will suffer from heart failure at some point. However, there can also be other reasons for heart failure, for example, consequential damage after heart disease.
The most common heart diseases with heart failure as a consequence include:

  • Heart attack
  • High blood pressure
  • Coronary heart disease
  • Congenital heart damage
  • Cardiac arrhythmia
  • Heart muscle inflammation

Most of these causes are heart disease, which can occur over time. Inflammation of the heart muscle, on the other hand, is much easier to prevent. Normally, inflammation of the heart muscle occurs when we overload our heart. For example, inflammation of the heart muscle often occurs when we do sport even though we are ill.


How does heart failure actually make itself felt? After a heart disease, you quickly notice whether your physical performance is limited. You can easily compare how you felt before and afterwards. In addition, after heart disease, the doctor treating you may diagnose additional heart failure.
If this is not the case, heart failure becomes noticeable through the following symptoms:

  • Everyday movements are significantly more strenuous than before
  • Limbs are permanently cold
  • Fluid in the lungs and an unpleasant cough
  • General breathing problems with shortness of breath up to and including possible breathlessness.
  • Sleep disturbances due to breathing problems
  • Water retention in the legs and feet
  • Lack of drive and feeling listless

How is it different from a heart attack?

As a rule, similar causes trigger the two heart diseases. But they differ in that heart failure is usually the result of a heart attack. In addition, in a heart attack, the narrowing of the coronary vessels is the trigger. Heart failure is a general weakness of the heart. In addition, heart failure can be an acute or chronic disease. Learn more about what happens in our body during a heart attack.

What are the different types of heart failure?

Heart failure can be divided into many different categories. For example, one can distinguish between left and right heart failure. There are also other ways to differentiate:

  • Global heart failure
  • Diastolic heart failure
  • Systolic heart failure

But you can also distinguish between acute and chronic heart failure.
Acute heart failure is a cardiac insufficiency that occurs at a moment’s notice. A few minutes or even hours are enough.
Chronic heart failure, on the other hand, is a prolonged cardiac insufficiency. Here, the disease has been present for several weeks, months or even years.

Severity of heart failure

Heart failure can be divided into four different degrees of severity. The stages are defined by the New York Heart Association (NYHA)

  • Severity 1: There are hardly any symptoms, but cardiac output is nevertheless limited.
  • Severity 2: Shortness of breath and fatigue occur after physical exertion.
  • Severity 3: The first symptoms appear after very light physical exertion.
  • 4. severity: the symptoms increase without any physical stress.

What is the life expectancy with heart failure?

Life expectancy naturally depends on the severity of the heart failure. If the heart failure is in severity grade I, life expectancy is still high. However, if it is severity III or IV, life expectancy is naturally much lower. Of course, no general guarantee can be given for the different degrees of severity. Every heart failure should be taken seriously and can mean far-reaching limitations. In order to increase life expectancy with heart failure, one can seek treatment.

What treatment is available for heart failure?

The treatment of heart failure varies from severity to severity. In addition, the treatment must be individually adapted to each patient. For example, pre-existing conditions of the heart and other pre-existing conditions play an important role. The treatment can be either a drug therapy or a surgical intervention. The intake of medication can counteract the heart failure to a certain extent.
Surgery, on the other hand, is usually only performed in cases of severe heart failure. Which treatment is optimal for my heart failure? You should discuss this question with your doctor. He or she can recommend an appropriate therapy, for example in the form of a cure.

Recognising a heart attack: What do you have to look out for?

A heart attack is one of the most common causes of death in a person. According to the Swiss Heart Foundation, around 30,000 people in Switzerland are affected by a heart attack every year. But when do you know if it is a heart attack? In this article you will learn how to recognise a heart attack in an emergency.

How do I recognise a heart attack?

First of all, the much more important question to ask is when a heart attack might occur in the first place. The signs of a heart attack are particularly bad if one eats an unhealthy diet or takes little exercise. But smoking can also have a negative effect on the heart.
But a heart attack is getting closer, especially in old age. The older we get, the weaker and older our hearts become. The heart vessels then slowly begin to close and a heart attack becomes more and more likely.
Finally, in order to recognise a heart attack in an emergency, the symptoms that occur are very important. But it is also important to take the symptoms seriously and call for help quickly. If you underestimate the signs of a heart attack, your chances of survival are not good.
From time to time, there are cases of what is called a mild or silent heart attack. This is a gradual heart attack that is often underestimated. However, to prevent this from happening, you should be able to recognise a heart attack.


You can recognise a heart attack as quickly as possible if you familiarise yourself with the signs. This way, you can quickly diagnose a heart attack when symptoms appear and get help accordingly. Dialing the emercency number should always be the first decision. If the first responders arrive quickly, the chance of survival also increases.
The most common symptoms include the following:

  • Severe pain in the chest area
  • Feeling of pressure in the chest area
  • Feeling of pressure spreads to other parts of the body such as arms or neck
  • Fear of death
  • Shortness of breath
  • Sweating
  • Pain does not get better

Other signs of a heart attack can also be, for example, a tingling in the left hand or a pain in the right upper arm. However, these signs are usually related to the other symptoms. If you experience these symptoms, you should call the emergency number and stay calm for the time being. If you are unable to dial the emergency number yourself, you should try to ask for help. It is important that the emergency call is made in any case. The only way to survive a heart attack is to get treatment at a hospital. In order to survive until you arrive at the hospital, you have to rely on the help of the first responders.
Note: With our app, it is even possible to request first aid via your smartphone. You can find out more about this right here.

Types of heart attack

With a heart attack, differences in severity can occur. As a rule, the symptoms occur so clearly that one can safely assume a heart attack. But there are cases in which a gradual heart attack occurs. In this case, one can assume a mild or silent heart attack.
The important thing here is to take the symptoms seriously and have yourself examined immediately. In this case, the same symptoms occur, but only in a weakened variant. Or there are only isolated symptoms that do not directly indicate a heart attack. For example, a slight pressure in the upper body or slight pain in the chest.
Nevertheless, one should not underestimate the symptoms. You should also be aware of the symptoms of a heart attack. Only then can you recognise a heart attack. With our app, for example, you can call for help in an emergency.

Risk factors heart attack

If you want to recognise a heart attack, you should also look at the risk factors. The risk factors can promote a heart attack by damaging the health and the heart. They can also help to prevent a heart attack. According to the Swiss Heart Foundation, nine out of ten heart attacks depend on various factors that you can influence yourself.
These include, among others:

  • Not enough exercise
  • Unhealthy diet
  • Smoking (including passive smoking)
  • Stress
  • High blood pressure
  • Overweight
  • Diabetes
  • Age

Many of the above-mentioned factors are within our control and we can also control them ourselves. Smoking in particular damages our body and not only our lungs. Even passive smoking can increase the risk of a heart attack. In other words, smoking not only harms our own bodies, but also those around us. Are you a regular smoker? Then you should stop now at the latest.
Instead, you should make sure you get enough exercise and keep your body moving. This will strengthen your body and your heart. It is not without reason that the heart of a competitive athlete is much larger than that of a normal person. You can also strengthen your body by eating a healthy and balanced diet. You can find many simple and healthy recipes for cooking on the internet. If necessary, you can ask your health insurance company for a diet plan. They usually offer a course for a balanced diet.
Then there are factors that we cannot necessarily influence. These include age or pre-existing conditions such as diabetes. Therefore, in these cases you should consult a doctor and discuss treatment options with him or her directly. In this way, you can prevent a heart attack in the best case.

Heart attack: What can you do in an emergency?

A heart attack can happen to anyone and can occur at any time. But what should I do in the event of a heart attack? How can I help others? In this article we provide the answers to these and other questions.

How can I help others with a heart attack?

Whether you are at a family party or alone on the street. Theoretically, a situation could arise at any time in which you are confronted with a heart attack. Because every year, about 30,000 people in Switzerland are affected by heart disease.
In order to be best prepared for such a situation, you should know what to do in case of an emergency. We have compiled a small guide that you should follow in the event of a heart attack.

  1. First pay attention to the symptoms and observe them to see if they persist or subside again.
  2. Stay calm and dial the emergency number (144). Report the situation and follow the instructions on the phone.
  3. Free the affected person from tight clothing on the upper body. This includes, for example, a tie, shirt or even a bra. Because a heart attack in a woman is not unlikely.
  4. Assign a person to wait outside for the first aiders to arrive.
  5. As soon as the affected person stops breathing and there are no signs of life, you should start resuscitation. Instructions for resuscitation can also be obtained from the emergency call.

If you follow these instructions, you can make a big contribution to first aid in the event of a heart attack. The most important thing is that you remain calm and also try to reassure the affected person. However, to be really sure whether it is a heart attack, you should know and observe the symptoms.
Note: Our Taris app is designed to help ensure first aid. You can find out more about it right here.


In order to recognise a heart attack in the first place, it is very important to observe the symptoms. The signs of a heart attack are very clear and unambiguous.
Heart attack symptoms include:

  • Severe pain in the chest area with an uplifting pressure.
  • The duration of the chest pain lasts longer than 15 min.
  • The chest pain spreads to other regions of the body, such as the shoulders and neck. But pain in the upper arm or a tingling sensation in the hand can also occur with a heart attack.
  • The pain does not get better and continues.

If these symptoms occur, you can be fairly certain that it is a heart attack. In addition, those affected usually experience a feeling of mortal fear and begin to sweat profusely. This is usually accompanied by shortness of breath, which increases the fear of death.
If this is the case, it is important to calm the person down. Calm breathing or a reassuring conversation can help. When the symptoms appear, you should immediately dial the emergency number. The faster the first responders arrive, the higher the chance of survival for the affected person.

What can I do if I have a heart attack?

Many people are prepared to act if another person is affected by a heart attack. But how does one actually behave when one’s own person suffers a heart attack? This question is very difficult to answer, as one actually has to deal with pain and fear of death.
First and foremost, it is important to get help as soon as possible. Either try to dial the emergency number yourself or ask someone else to do so. In addition, you should not underestimate the symptoms. The sooner you make the emergency call yourself or ask someone to help you, the sooner first aid will arrive.
Then you should make sure that you stay calm and try to breathe calmly. The more you panic, the stronger the symptoms can become. You should also be aware that help is already on the way. This can also help to calm yourself down.
If the first aiders arrive, one should try to follow the instructions to help the medical staff with the treatment. You will then be taken to the nearest hospital for further treatment.

What is the chance of survival?

If you arrive at a hospital as quickly as possible, the chances of survival after a heart attack also increase. Medicine is now so well developed that it is possible to react very well to a heart attack. Of course, good first aid is also a prerequisite.

Heart attack Doccheck

If you suffer a heart attack and survive, you should definitely have yourself examined further by a doctor. The cause of the heart attack can usually be determined. After that, it is clear that further treatment is unavoidable. As a rule, one has to adjust one’s diet or take more exercise. But treatment with medication cannot be ruled out either. The attending physician then orders further treatment after the heart attack.

Heart attack treatment

There are different ways to treat a heart attack. Immediately after a heart attack, the patient is usually given a catheter in hospital. This involves fitting the patient with a stent. The stent dilates the affected heart vessel so that blood can flow through it again. This is because a blocked coronary vessel usually causes a heart attack.
After the treatment in hospital, the treatment continues. There are different treatment options. For example, you can take a course of treatment to strengthen your heart again. This can at least prevent another heart attack. You can discuss other treatment options with your doctor.

Anatomy of the heart: how does our heart really work?

A heart keeps the human body alive and functioning without interruption. But how exactly is the heart built and how does it work? In this article we will take a closer look at the anatomy of a person’s heart.

How does the heart work?

The heart is one of the most important organs in our body and keeps us alive. It never stops and cannot afford to take a break. Even during sleep, the heart continues to beat diligently.
And the anatomy of the heart is actually simpler than it seems at first glance. That’s because our heart works like a pump, or rather, like a bicycle pump. Instead of air, the heart pumps blood throughout our body.
This is also called the cardiovascular system. Now, the cardiovascular system can be divided into two different circuits. First, there is the systemic circulation, which is the larger circulation. And the smaller circulation is the pulmonary circulation.
The most important components of the cardiovascular system are the arteries and veins. Veins are usually represented with the colour blue and arteries with the colour red. Veins flow towards the heart and contain deoxygenated blood. Arteries, on the other hand, run away from the heart and contain oxygenated blood. There is one exception: the pulmonary vein is supplied with oxygen-rich blood and the pulmonary artery with oxygen-poor blood.

Pulmonary circulation

  1. In a person’s pulmonary circulation, the heart pumps deoxygenated blood from the right ventricle into the pulmonary artery. The pulmonary artery then divides into many different small arteries. As it does so, the small arteries branch into even smaller arterioles and then eventually into capillaries. Capillaries are very small vessels in the human body.
  2. Once the deoxygenated blood has reached the capillaries of the lungs, gas exchange takes place there. This is because deoxygenated blood is also rich in carbon dioxide. Thus carbon dioxide is released through the lungs and incidentally oxygen is taken up through respiration.
  3. Since the blood has now been supplied with oxygen, it now takes the route through the veins. In the process, the oxygen-rich blood flows through the small venules until it reaches the larger veins and finally the pulmonary vein. The pulmonary veins are connected to the left atrium of the heart and supply it with oxygen-rich blood.
  4. The blood then enters the wider systemic circulation.

Circulation of the body

  1. From the left side of the heart, blood flows through the aortic valve into the aorta. The aorta is also called the main artery.
  2. Arriving at the aorta, the blood passes into the arteries. These in turn branch off into smaller arterioles to the capillaries in the head and body. Here again an exchange of oxygen takes place, this time with the cells of the body tissues.
  3. In the process, the cells are supplied with oxygen and important nutrients. Meanwhile, the blood absorbs carbon dioxide and waste products from the cells.
  4. Thus, the now oxygen-depleted blood is once again delivered to the body through the venules and veins. There, the deoxygenated blood finally enters the right ventricle and the cardiac cycle starts again from the small pulmonary circulation.

Did you know that? There are also interesting facts about the anatomy of the heart. For example, if you add up the length of all the blood vessels, you get a total length of about 90,000-100,000 km. That’s almost twice the circumference of our earth.

How does the heart beat?

While the heart is busy pumping like a bicycle pump, the heart continues to contract. When it contracts, it transports blood through the blood vessels in the body. When the heart relaxes, it fills with blood. The heart is a muscle. This makes the heart one of the strongest muscles in our body.
When the heart contracts, we perceive it as a heartbeat. If you touch your chest, you feel a strong heartbeat. As a rule, the heart beats between 50 and 80 times per minute. In special situations, the heart can even beat up to 200 times per minute.
Basically, a heartbeat is divided into systole and diastole. Systole is the tension phase of the heart. Diastole is the heart’s relaxation phase. In general, the heart handles this by means of electrical impulses that are formed in the sinus node. The sinus node is the heart’s natural pacemaker.

Anatomy of the heart: how is the heart built?

A human heart is usually the size of a fist and is located approximately in the centre of our chest. And not so many assume on the left side of the chest. This is because about 2/3 of the heart is located on the left side of the chest. The remaining 1/3 is on the right side. Sometimes a human heart can be bigger than a fist. This is often the case with athletes. This is because athletes or sportsmen and women need a high level of endurance in the sporting activities they do.

Structure of a human heart

The heart is also called a hollow body because it is a muscle that is hollow. The heart is divided by a septum into two halves, the left and right halves of the heart. Both halves consist of a small atrium and a ventricle.

The hollow body consists of the following components:

  • Heart valves
  • Ventricles
  • Coronary arteries
  • Ventricular septum
  • Hollow vein
  • Aorta
  • Pulmonary veins
  • Pulmonary artery
  • Atrium

Healthy heart: What is healthy for the heart?

With age, the risk of heart disease also increases. But it is not only age that plays a decisive role here. Nutrition and general lifestyle are also important for a healthy human heart. But what exactly is good for our heart and how does it become a healthy heart? In this article we answer these and other questions.

What is healthy for the heart?

You can do good things for your healthy heart with very simple means. And not just since today, but from an early age. Our heart already benefits from a little sport when we are children. If we grow up with sport and keep moving regularly, it also keeps our heart fit. That’s why it stands to reason that the heart of a competitive athlete is usually bigger than an average heart. The heart is a muscle and can be trained. Normally, the human heart is the size of a clenched fist. In competitive athletes, however, the heart is usually somewhat larger.
But you don’t have to be a competitive athlete to do something good for your heart. The two most important factors are exercise and a healthy nutrition. The earlier you start, the better it is for your body and especially for your heart. The later you start, the harder it is for the heart to regenerate. Nevertheless, the motto is: It is never too late! The heart can recover quickly and also rebuild itself. Nevertheless, you have to approach the matter with a lot of patience. Because everything does not get better overnight
Age also plays a very important role in the heart. When you are still very young and fit, a poor nutrition and little exercise are hardly noticeable. Only with age do you feel the consequences of a less good lifestyle. The older a person gets, the more attention he or she has to pay to his or her body and also to his or her heart. To avoid heart problems in old age, you have to strengthen your heart. Now you can find out the best way to do this.

What strengthens the heart?

As mentioned, the two most important factors for the heart are a healthy nutrition and some exercise. The sooner you start, the more the heart will benefit. But take a calm and relaxed approach to the whole thing. It takes a lot of patience to strengthen your heart. But now to the actual question: What is good for a healthy heart and how can I strengthen my heart?


The most common cause of death in Switzerland is coronary heart disease. And it has been proven that regular exercise of the body reduces the risk of the disease. But how much exercise is necessary and when is it too much? There is no general answer to this question. It always depends on the circumstances and these vary from person to person. The decisive factors are age, how fit you feel and any pre-existing conditions. Even the smallest things make a difference.
Nowadays we live in a very technologically advanced time and everything is made easier for us. We no longer have to use stairs and are transported by escalators. And the list goes on forever. But if you already do without the escalators and walk the stairs yourself, then you have already done a lot for your body. Besides, it is always good for the body to take a walk. It is also enough to enrol in small sports courses and attend them regularly. These do not always have to be intensive, but can also be more relaxed, such as yoga or similar.

Healthy nutrition

Besides sport and exercise, the right nutrition is also very important for the heart. A healthy and above all balanced nutrition can strengthen the heart. Fast food, snacks and overeating can not only harm the body, but also a heart. A poor nutrition often leads to high blood sugar or blood fat levels.
Many people may still know it from their school days, namely the food pyramid. This basically depicts everything important that you need to know. But if you would like more information or even nutritional advice, that is no problem. Your health insurance company usually offers special courses or personal nutrition counselling. Often, they will also draw up a special diet plan that is tailored to you.

What is bad for the heart?

Now you have learned what options you have to strengthen your heart. But it is also important to know which factors can damage the heart quickly and in the long term. These include the following things:

  • Stress
  • Overweight
  • Smoking
  • High blood pressure
  • Age
  • Pre-existing conditions
  • Hereditary diseases

Many factors play a role when it comes to damaging the human heart. But there are many things you can change yourself. In the best case, you have never smoked and will not start. But if you have been or are a regular smoker, now is the time to quit. It is clear that you cannot simply stop from one day to the next. Even small successes are beneficial for the heart.

What diseases are there for the heart?

Now the question arises as to which diseases can be the consequence. Because many diseases are not known at first. Thus, many people take heart disease lightly and do not feel affected by it. But reality catches up with you sooner than you might think.
The most common heart diseases include the following:

  • Coronary heart disease
  • Cardiac arrhythmia
  • Heart attacks
  • and much more.

Heart attack: This is what happens in the body during a heart attack!

One of the most common causes of death is a heart attack. But what exactly is a heart attack and how does it happen? In this article we answer these questions and more.

What is a heart attack?

A heart attack is a disease of the heart that often occurs in old age. This is because the heart muscle tissue decreases over the years and a heart attack becomes more likely. A heart attack or myocardial infarction should not be underestimated and is an absolute emergency situation. That is why you must act quickly if you have clear symptoms and, if necessary, provide first aid.

What happens during a heart attack?

Basically, a heart attack occurs when the heart wall is no longer supplied with blood properly. The heart wall is then no longer supplied with blood properly as soon as the coronary vessels begin to close. Depending on the severity of the heart attack, the coronary vessels are only partially or completely closed. But why do the coronary vessels close? With age, calcium deposits and blood fats accumulate on the walls of the coronary vessels. As a result, the coronary vessels can no longer supply the heart properly with oxygen and blood. The result is ultimately a heart attack.

How is this different from heart failure?

The term heart failure is also often mentioned in connection with heart disease. But many people do not really know what heart failure is. In principle, it is a heart failure, just like a heart attack. In heart failure, however, the heart is no longer able to pump blood through the body. The difference to a heart attack is mainly in the symptoms. Typical symptoms are shortness of breath or fatigue. With a heart attack, on the other hand, the symptoms are much more noticeable and severe.

Symptoms of a heart attack?

The most important thing is to recognise a heart attack and its signs as early as possible. Sometimes it only becomes noticeable gradually and you don’t know that it is a heart attack. And sometimes the symptoms are so clear that you can safely assume it is a heart attack. As a rule, the sequence of events is as follows:

  • The chest begins to hurt and enormous pressure builds up. The pain usually lasts longer than 15 minutes.
  • The chest pain spreads and affects other parts of the body, such as the shoulders, arms, neck and jaw. A heart attack is also noticeable through pain in the upper arm or tingling in the hand.
  • The pain continues and does not go away.

If this is the case, you should dial the emergency number as soon as possible and request help. As a rule, an emergency doctor will then set off as quickly as possible. In the meantime, you can give first aid if necessary. Stay calm and wait for the instructions of the emergency caller.
Other symptoms may include:

  • Shortness of breath
  • Fear of death
  • Pale face
  • Nausea
  • Sweating
  • General feeling of weakness

Causes of a heart attack?

Now the only question is how a heart attack occurs. The most common cause is age-related, as the heart becomes weaker and more vulnerable with age. Poor diet and little exercise can lead to pre-existing conditions such as arteriosclerosis. This is all the deposits on the arteries, which in turn narrow them. As a result, less blood flows through the body and you yourself are more susceptible to heart attacks. Smoking or an unhealthy lifestyle can also have a negative effect on the heart. That is why you should regularly have yourself examined by a doctor for possible diseases.

Prevent heart attack

You should make sure that you avoid as much stress as possible in everyday life. The job can often demand a lot from us, but you are not doing the body much good.

  • Make sure you eat a balanced and healthy diet so that you can strengthen your body and your heart.
  • Keep moving and do enough sports, so you can additionally strengthen the body.
  • But all pre-existing conditions can also damage the rest of the body and especially the heart over time. If you are affected by pre-existing conditions, you should discuss them with your doctor.
