Using the Blood Pressure Monitor (Cont.)
Irregular Heartbeat Detector
An irregular heartbeat is detected when a heartbeat
rhythm varies while the monitor is measuring
systolic pressure and diastolic pressure. During
each measurement, the monitor will keep a record
of all the pulse intervals and calculate their average
value. If there are two or more pulse intervals and the
difference between each interval and the average is
more than ±25%, or if there are four or more pulse
intervals and the difference between each interval
and the average is more than ±15%, then the irregular
heartbeat symbol will appear on the display with the
measurement result.
Caution:
• The appearance of the irregular heartbeat 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 this monitor does not replace a
38
cardiac examination, but serves to detect pulse
irregularities at an early stage.
Why does my blood pressure fluctuate
throughout the day?
• Individual blood pressure varies throughout the
day. It is also affected by the way you tie your cuff
and your measurement position, so please take
measurements under the same conditions each
time.
• If you take medicine, your blood pressure will vary
more.
• Wait at least 3 minutes between measurements.
