13.1 Irregular heartbeat (IHB)
The appearance of this symbol "IHB" signifies that a certain pulse irregularity was
detected during measurement.
Talking, moving, shaking or an irregular pulse during the measurement can result in the
appearance of this icon.
Usually this is not a cause for concern, however if the symbol appears often, we
recommend you seek medical advice.
And please note that the device does not replace a cardiac examination, but serves to
detect pulse irregularities at an early stage.
The irregular heart beat detected record wont be stored in memory.
The pulse display is not suitable for checking the frequency of heart
pacemarkes. If a certain pulse irregularity is detected during
measurement often, we recommend you seek medical advice.
However, as a safeguard, we recommend that if you have arrhythmias
such as atrial or ventricular premature beats and atrial fibrillation or
any other special conditions you should check with your physician
before using your device.
The IHB function is not designed for use by people with arrhythmias
nor for diagnosing or treating an arrhythmic problem. In order to filter
the unstable status of user and avoid affecting the detection of heart
rate from any movement, shaking or talking in the beginning of
measurement, the method of averaging heart beat intervals for subject
device is calculated with the three proper heart beat pulses detected in
the beginning of measurement and that is different from a strict
mathematical averaging of all recorded intervals.
At least 3 beats with at least 25% difference from the average heart beat
interval will generate the IHB icon on the screen.
