What is Irregular Heartbeat?
An irregular heartbeat is a heartbeat
rhythm that varies by more or less
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 notify your
doctor. Conducting self-diagnosis and treatment based on measurement results
is dangerous. Be sure to follow the instructions of your doctor.
