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 display 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.
If the irregular heartbeat symbol ( ) is shown frequently, please let
your doctor be aware of it. Self-diagnosis and treatment based on
measurement results is dangerous. Be sure to follow the instructions of
your doctor.
