What are systolic pressure and diastolic
pressure?
When ventricles contract and pump blood out of the heart,
blood pressure reaches its maximum value, the highest
pressure in the cycle is known as systolic pressure. When
the heart relaxes between heartbeats, the lowest blood
pressure is diastolic pressure.
What is the standard blood pressure
classification?
Below illustrates the blood pressure classification mode by
World Health organization (WHo) and international
society of Hypertension(isa) in 1999.

CautIon
only a physician/GP can tell you your normal blood pressure range and the point at which you are at risk.
consult your physician to obtain these values. if the measurements taken with this product fall outside the
range, consult your physician/GP.

Irregular Heartbeat Detector
An irregular heartbeat is detected when a heartbeat rhythm varies while the unit is measuring the systolic
and diastolic blood pressure. during each measurement, this equipment records the heartbeat intervals and
works out the standard deviation. if the calculated value is larger than or equal to 15, the irregular heartbeat
symbol appears on the symbol when the measurement results are displayed.
CautIon
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.
