What are systolic pressure and diastolic pressure?
When ventricles contract and pump blood
out of the heart, the blood pressure reaches
its maximum value in the cycle, which is
called systolic pressure. When the ventricles
relax, the blood pressure reaches its minimum
value in the cycle, which is called diastolic
pressure.
What is the standard blood pressure classification?
The blood pressure
classification published
by World Health Organization
(WHO) and International
Society of Hypertension
(ISH) in 1999 is as follows:
Only a physician can tell your normal BP
range. Please contact a physician if your
measuring result falls out of the range.
Please note that only a physician can tell
whether your blood pressure value has
reached a dangerous point.
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.

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.
