WHAT IS AN IRREGULAR HEARTBEAT
aBoUt CUFF inFLation mEtEr
The UA-789 monitor provides a blood pressure and pulse rate mea-
surement even when an irregular heartbeat occurs. The irregular
heartbeat symbol will appear in the display window in the event
an irregular heartbeat has occurred during measurement. An irregular
heartbeat is defined as a heartbeat that varies by 25% from the aver-
age of all heartbeat intervals during the blood pressure measurement.
It is important that you relax, remain still and refrain from talking
during measurements.
notE: We recommend contacting your physician if you see this
symbol frequently.
The Cuff Inflation Meter is located on the left side of the display
screen to tell you when the blood pressure monitor is inflating and
deflating the cuff. The Cuff Inflation Meter moves up during inflation
and moves down during deflation.
