CAUTION
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.
Maintenance
What are systolic pressure and diastolic pressure?
To obtain the best performance, please follow instructions below.
When ventricles contract and pump blood out
of the heart, the blood pressure reaches its
maximum value in the cycle, which is called
systolic pressure. When the ventricles relax,
the blood pressure reaches its minimum
value in the cycle, which is called diastolic
pressure.
What is the standard blood pressure classification?
The chart on the right
illustrates the blood
pressure classification
mode by American Heart
Association (AHA).
The AHA recommends
the following guidelines
for upper limit of normal
blood pressure readings
at home.
AHA Home Guideline for Upper Limit of Normal
BP
Systolic Blood Pressure
135 mm Hg
Diastolic Blood Pressure
85 mm Hg
Irregular Heartbeat Detector
An irregular heartbeat is detected when a heartbeat rhythm varies while the unit is
measuring the systolic and diastolic blood pressure. During each measurement,
this equipment records the heartbeat intervals and works out the standard deviation.
If the calculated value is larger than or equal to 15,the irregular heartbeat symbol
appears on the symbol when the measurement results are displayed.
