An irregular heartbeat is detected when a heartbeat rhythm varies while the
device is measuring systolic pressure and diastolic pressure. During each
measurement, blood pressure monitor will keep a record of all the pulse
intervals and calculate the average value of them. 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%, then the irregular heartbeat symbol will appear
on the display with the measurement result.
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.
What are systolic pressure and diastolic pressure?
Irregular Heartbeat Detector
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.

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.
