What is Irregular Heartbeat?
An irregular heartbeat is a 
heartbeat rhythm that varies by 
more than 25% from the average 
heartbeat rhythm detected while 
the unit is measuring the systolic 
and diastolic blood pressure.
If such an irregular rhythm is 
detected more than twice during 
measurement, the irregular 
heartbeat symbol (   ) appears on the symbol when the 
measurement results are displayed. 
What is Arrhythmia?
A heartbeat is stimulated by electrical signals that cause the heart 
to contract.
Arrhythmia is a condition where the heartbeat rhythm is abnormal 
due to flaws in the bio-electrical system that drives the heartbeat. 
Typical symptoms are skipped heartbeats, premature contraction, 
an abnormally rapid (tachycardia) or slow (bradycardia) pulse. This 
can be caused by heart disease, aging, physical predisposition, 
stress, lack of sleep, fatigue etc. Arrhythmia can only be diagnosed 
by a doctor through a special examination.
Whether the appearance of the irregular heartbeat symbol 
(   ) in the results indicates arrhythmia or not can only be 
determined by an examination and diagnosis by your doctor. 
Warning: 
If the Irregular heartbeat symbol 
(  ) is shown frequently, please 
make your doctor aware of it. Conducting self-diagnosis and 
treatment based on measurement results are dangerous. Be sure to 
follow the instructions of your doctor.
