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.
Irregular Heartbeat Detector (
)
This Wrist Blood Pressure Monitor is equipped with an intelligent function of Irregular Heartbeat (IHB)
Detector. During each measurement, this equipment records the heartbeat intervals and works out the
standard deviation. If the heartbeat intervals compare with the average intervals, the deviation more than
3 is over 25% or more than 5 is over 15%, this equipment will light up the IHB symbol on the screen when
displaying the measuring result.
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.
