ABOUT BLOOD PRESSURE
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:
CAUTION
Only a physician can tell your normal BP range. Please
contact a physician if your measuring result falls out of the
range. Kindly note that only a physician could 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, the monitor records all the pulse intervals and calculate the
average; if there are two or more pulse intervals,the difference between each interval and the average is more than
the average value of ±25% , or there are four or more pulse intervals, the difference between each interval and the
average is more than the average value of ±15%,the irregular heartbeat symbol appears on the display when the
measurement results have appeared.
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.
