ABOUT IRREGULAR HEARTBEAT [IHB]

An irregular heartbeat is defined as a heartbeat that varies by 25%
from the average of all heartbeats during the blood pressure
measurement. When the device detects an irregular heartbeat two
or more times during the measurement, the Irregular Heartbeat
indicator will appear on the display.
It is important that you are sitting relax, steadily and stay quite
during the measurement.

If the irregular heartbeat indicator displays frequently after
the measurement, you are recommended to consult your
physician.

ABOUT BLOOD PRESSURE

What Is Blood Pressure?
Blood pressure is the force exerted by blood against the walls of the
arteries. Systolic pressure occurs when the heart contracts.
Diastolic pressure occurs when the heart expands. Blood pressure
is measured in millimeters of mercury (mmHg). One’s natural blood
pressure is represented by the fundamental pressure, which is
measured first thing in the morning while one is still at rest and
before eating.

What Is Hypertension And How Is It Controlled?
Hypertension, an abnormally high arterial blood pressure, if left
unattended, can cause many health problems including stroke and
heart attack. Hypertension can be controlled by altering one’s
lifestyle, avoiding stress, and with medication under a doctor’s
supervision. To prevent hypertension or to keep it under control:

• Do not smoke

• Exercise regularly

• Reduce salt and fat intake

• Have regular physical checkups

• Maintain proper weight
