An irregular heartbeat is present when the heart rhythm deviates from
the average heart rhythm by more than 25 %. 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 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. A 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.
