ABOUT BLOOD CIRCULATION AND PRESSURE
IRREGULAR HEARTBEAT?

Blood circulation is responsible for supplying the body with
oxygen from the lungs. During each heartbeat cycle, the blood
pressure exerted on the arteries varies between a maximum
(systolic) and a minimum (diastolic) pressure.
The systolic blood pressure value (higher pressure or top value)
represents the blood pressure produced by the heart muscle
when it contracts and pumps the blood out of the heart.
The diastolic blood pressure value (lower pressure or lower
value) represents the blood pressure produced in between
heartbeats when the heart muscle relaxes.
Lower pressure
Relaxation of the
heart muscle
Pressure decreased
on arteries
Blood returns to heart
Higher pressure
Contraction of
the heart muscle
Pressure increased

Systolic Blood Pressure
An irregular heartbeat is defined as a heartbeat that varies by
25% from the average of all heartbeat intervals while the unit is
measuring the systolic and diastolic blood pressure.
This Blood Pressure Monitor is equipped with an intelligent
Irregular Heartbeat (IHB) Detector. During each measurement,
the monitor records the heartbeat intervals and works out the
standard deviation. If the calculated value is larger than or
equal to 15, this device will record an IHB.
If an irregular rhythm is detected more than twice during
measurement, the irregular heartbeat symbol with three
hearts will appear on the display along with the
measurement results.
Note: The appearance of the IHB icon indicates that a pulse
irregularity consistent with an irregular heartbeat was
detected during measurement. Usually this is NOT a cause
for concern. However, if the symbol appears often, we
recommend you seek medical advice. Please note that the
device does not replace a cardiac examination, but serves
to detect pulse irregularities at an early stage. Do not use
this device as a substitute for proper medical diagnosis and
check-ups by your physician.
