Irregular Heartbeat Indicator
If an irregular heartbeat is detected during measurement, the Irregular
Heartbeat (IHB) Indicator is displayed after measurement is completed.
There are 2 conditions under which the signal of IHB will be displayed:
1) The coefficient of variation (CV) of pulse period > 25%
2) The difference of adjacent pulse period 0.14s, and the number of such
pulse takes more than 53 percentage of the total number of pulse.
• Measurement may not be correct if your heartbeat fluctuates greatly during
measurement. If the Irregular Heartbeat (IHB) Indicator is displayed, measure your blood
pressure again.
Caution
If the Irregular Heartbeat (IHB) Indicator appears frequently,
you are advised to consult a doctor about your health
condition.

Technical Alarm Description
The monitor will show ‘HI’ or ‘Lo’ as technical alarm on LCD with no delay if the
determined blood pressure (systolic or diastolic) is outside the rated range specified
in part SPECIFICACIONS. In this case, you should consult a physician or check if
your operation violated the instructions.
The technical alarm condition (outside the rated range) is preset in the factory and
cannot be adjusted or inactivated. This alarm condition is assigned as low priority
according to IEC 60601-1-8. The technical alarm is non-latching and need no reset.
The signal displayed on LCD will disappear automatically after about 8 seconds.
