In a heart rhythm disorder, the normal heart rate is disturbed by various causes. Read all about it.


at Herzrhythmusstörungen The normal heart rate is disturbed by various causes. The heart then beats either too slowly (bradycardia), too fast (tachycardia) or irregularly (arrhythmia). There are glitches in the formation of electrical impulses designed to trigger a heartbeat and disturbances in the transmission of these impulses. Read how cardiac arrhythmias differ and how to recognize them.

ICD codes for this disease: ICD codes are internationally valid codes for medical diagnosis. They are found e.g. in doctor's letters or on disability certificates. R00I48I46I47I49I45I44

Heart rhythm disorders: where do they come from?

Normally, the so-called sinus node, a small area in the atrium, produces electrical impulses to the heartbeat. These are conducted via the somewhat lower AV node into the heart chambers. Cardiac arrhythmias can occur if the sinus node does not generate the electrical impulses properly, the impulses are not properly routed, or additional impulses are created in the atrium or the chamber. There are dangerous and also dangerous cardiac arrhythmias.

Cardiac arrhythmia: what is there

    The deadliest heart disease

    Heart attack, sudden cardiac death, atrial fibrillation - most people in Germany die from heart disease. Read here which symptoms you are causing and which heart diseases are particularly dangerous.

    coronary heart desease

    Six million Germans have coronary heart disease (CHD). It is the cause of many other heart diseases such as heart failure, heart attack or sudden cardiac death. In the case of KHK, "liming" the blood vessels that supply the heart muscle with oxygen. Medically, it is an arteriosclerosis of the coronary arteries. The result is a lack of blood flow and a concomitant lack of oxygen in some parts of the heart muscle.

    Angina pectoris means as much as chest tightness. Typical of this is a sudden pain in the heart and a feeling of tightness, burning or pressure in the chest. It is not an autonomic disease but a major symptom of coronary heart disease. In case of sudden chest pain, you should call an emergency doctor immediately. Because only a doctor can determine if it is possibly a heart attack.

    Heart attack

    112 - a heart attack is always an emergency. It arises when a blood vessel of the heart is blocked by a blood clot. Within a short time, the heart muscle is no longer sufficiently supplied with oxygen. Failure to reopen the sealed vessel within a very short time will cause the area served by the vessel to die. Every year around 280,000 Germans suffer a heart attack. The main cause is a CHD.

    Around 1.8 million people in Germany suffer from heart failure, also called heart failure. In this disease, the pumping power of the heart muscle is weakened. Then the whole body is no longer sufficiently supplied with blood and oxygen. At an advanced stage, the patient will experience shortness of breath, water retention and weakness even at low levels of stress. The most common causes of heart failure are CHD and high blood pressure.

    If the heart is out of rhythm, it is called cardiac arrhythmia. The heart beats too fast, too slowly or irregularly. There are many causes. Most often, however, is a coronary heart disease behind it.

    atrial fibrillation

    In atrial fibrillation, the heart beats irregularly.This is the most common form of a disturbed heart rhythm: one million Germans suffer - but more than half of them do not notice it. Some feel a stumble or tachycardia and suffer from dizziness, shortness of breath, chest pain or anxiety. Atrial fibrillation may also develop into heart failure. Most importantly, in patients with atrial fibrillation, clots form in the heart - then a stroke threatens.

    Tachycardia, also referred to as tachycardia by medical professionals, is a cardiac arrhythmia in which the heart beats permanently very quickly - more than 100 beats per minute. Various diseases can accelerate the heartbeat, including atrial fibrillation, CHD and high blood pressure. If your heart beats too fast, see a doctor. Because heart racing can also cause a sudden cardiac death.

  • Picture 9 of 11


    The counterpart to tachycardia is bradycardia. Here, the heart beats too slowly: the heart rate is below 60 beats per minute. Sometimes the heart rate is so low that too little blood is pumped into the systemic circulation. As a result, the oxygen demand, especially of the brain, can no longer be adequately met. Headaches, dizziness, unconsciousness, nausea and vomiting can all be the result.

    ventricular fibrillation

    Ventricular fibrillation is an often fatal cardiac arrhythmia. It arises when the electrical signals that control the work of the heart are severely disturbed. Then frequencies of up to 800 signals per minute can occur - an effective heartbeat is then no longer possible. The result: cardiac arrest and unconsciousness. Only an immediate chest compressions followed by defibrillation can save your life.

    Sudden cardiac death

    A sudden cardiac death unexpectedly rips a person from life. 100,000 to 200,000 people in Germany aspire to it every year. It is always caused by a severe heart arrhythmia. The affected person suddenly becomes unconscious because his brain is no longer supplied with oxygen - it dies within a short time.

Cardiac arrhythmia: sports

Especially in children and young people, the heart rate increases and decreases during inhalation and exhalation. These changes are called the heart rate sinus arrhythmia. This process is normal and requires no therapy. In sports sometimes extra beats of the heart, so-called extrasystoles. They are partly unpleasant, but mostly harmless.

Cardiac arrhythmia: treatment

If a tachycardia occurs very suddenly, it is also possible to first try whether certain maneuvers can slow the heart rate. For example, you can put an envelope with ice on your face, or with your breath held down. This partially reduces the heartbeat.

In case of frequent tachycardia, unpleasant "heart pains", dizziness or fainting always a doctor should be consulted, who can control the rhythm of the heart. The most important examination for suspected cardiac arrhythmias is the electrocardiogram (ECG). This records the electrical currents of the heart.

Some cardiac arrhythmias require no therapy. Sometimes medication must be taken to prevent the arrhythmia. In cardiac arrhythmias that make the heart beat too slowly, sometimes a pacemaker must be implanted.

  • Ablation at the heart
  • Pacemaker
  • ICD implantation
  • cardioversion
  • resuscitation

Cardiac arrhythmia: consequences

Some arrhythmias are harmless, others dangerous. If a heart rhythm disorder lasts longer, this can have some consequences. The heart becomes weaker, the risk of stroke increases. A sudden cardiac death is possible.
