An irregular heartbeat is present when the heart rhythm deviates by
more than 25 % from the average heart rhythm. The contraction of the
heart muscle is stimulated by electrical signals. A disorder of these
electrical signals is called an arrhythmia. This may be due to a genetic
predisposition, stress, age, lack of sleep, exhaustion or similar factors. A
doctor can establish whether an irregular heartbeat is the result of an
arrhythmia.
Heart rhythm disorders are disturbances of the normal rate or rhythm of the
heartbeat. Distinction should be made between mild and severe heart rhythm
disorders. This can only be determined by a special examination carried out by a
doctor.
