IRREGULAR HEARTBEAT DETECTOR (IHB),
CONTINUED
T o determine the presence of an irregular heartbeat,
the average of the heartbeat intervals is calculated
with the first 3 normal effective heart beat values. It
is important to note that the average is not a strict
mathematical averaging of all recorded intervals. At
least 3 beats with 25% or greater difference from the
average heart beat interval will generate the icon
on the screen.
IMPORTANT INFORMATION:
This blood pressure monitor is not designed for use
by people with arrhythmias nor for diagnosing or
treating an arrhythmia problem. 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 blood pressure
monitor.
