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 are appeared.
The appearance of the IHB icon indicates that a pulse irregularity
consistent with an irregular heart-beat 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.

1. Individual blood pressure varies
multiple times everyday. It is also
affected by the way you tie your cuff
and your measurement position, so
please take the measurement under
the same conditions.
2. If the person takes medicine, the
pressure will vary more.
3. Wait at least 3 minutes for another
