Cardiac arrhythmias – when your heart loses its rhythm

Normally the heart beats regularly, that is, rhythmically. But if the heart is unable to keep a regular beat, then it is referred to as a heart rhythm disorder. Often the patient may feel harmless extra beats which are clinically insignificant. But a heart-rate deceleration (bradycardia) or acceleration (tachycardia) can be life-threatening.

The sinoatrial node - the pulse generator of the heart

A normal, regular heartbeat, also called a sinus rhythm, arises in the so-called sinoatrial node. The sinoatrial node consists of special cardiac muscle cells which lie in the right atrium. It is the metronome or pacemaker of the heart and is the source of a regular heartbeat. By altering the nerve impulses, and the hormones and the composition of the minerals in the blood, the rate and the force of the heart beats can be adjusted as necessary for the current load situation.

Impulses generated from the sinoatrial node are transmitted to the atrioventricular node (AV node). The AV node has a regulatory role in the heart and slows very rapid impulses from the atria, and acts as an additional pacemaker in case of failure of the sinus node. Special heart muscle fibers conduct impulses from the AV node to the heart muscle itself so that the heart can contract. The normal heart rate for an adult is usually between 60 and 100 beats per minute. A heart rate of less than 60 beats per minute is called bradycardia, and a heart rate greater than 100 beats per minute min is called tachycardia. Well-trained athletes can have a heart rate below 50 beats per minute, without being lethal. On the other hand, in stress situations (e.g. athletic activity) heart rates above 100 beats per minute are normal.

As a rule, the heart rate can be determined by measuring your pulse. Modern blood pressure monitors can determine not only the blood pressure but also the heart rate (pulse). In principle, almost any artery disease, as well as hormonal disorders or any disease which affects the composition of the blood can lead to arrhythmias.

Generally one can differentiate between bradycardic and tachycardic arrhythmias and regular and irregular rhythmic disturbances. On the following pages we offer explanatory information on complex, special topics such as cardiac arrhythmias during pregnancy or cardiac arrhythmias in athletes.
