things to know about blood pressure

What are systolic pressure and diastolic pressure?
When ventricles contract and pump blood out of the heart, blood
pressure reaches its maximum value, the highest pressure in the
cycle is known as systolic pressure. When the heart relaxes between
heartbeats, the lowest blood pressure is diastolic pressure.
CAUTION:
Only a physician can tell your normal blood pressure range. Please
contact a physician if your measuring result falls out of the range.
Please note that only a physician can tell whether your blood pressure
value has reached a dangerous point.

Irregular heartbeat detector
An irregular heartbeat is detected when a heartbeat rhythm varies while
the device is measuring systolic pressure and diastolic pressure.
During each measurement, the blood pressure monitor will keep
a record of all the pulse intervals and calculate the average value of
them. If there are two or more pulse intervals, the difference between
each interval and the average is more than the average value of ± 25%,
or there are four or more pulse intervals, the difference between
each interval and the average is more than the average value of ±15 %,
then the irregular heartbeat symbol will appear on the display with the
measurement result.
