Irregular Heartbeat Detector (IHB)

The symbol will appear on the display, indicating a certain heartbeat irregularity was detected
IHB
during measurement. The heartbeat rhythm that is more than or less than 25% from the average rhythm
is usually defined as an irregular heartbeat rhythm. Talking, moving, shaking or an irregular pulse
during the measurement can result in the appearance of this symbol.
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.
• No Irregular Heartbeat Detector measurement will 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.
