What are systolic pressure and diastolic pressure?

What is the standard blood pressure classification?
Irregular Heartbeat Detector
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.
The blood pressure classification
published by World Health Organization
(WHO) and International Society of
Hypertension (ISH) in 1999 is as follows:
CAUTION:
Consult a physician for 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.

An irregular heartbeat (IHB) is detected when a heartbeat rhythm varies while the unit is mea-
suring the systolic and diastolic blood pressure. During each measurement, the monitor records
the heartbeat intervals and calculates the average. If any average is larger than or equal to 25%,
the irregular heartbeat symbol appears on the display when the measurement results appear.
CAUTION:
The appearance of the IHB icon indicates that a pulse irregularity consistent with an irregular heart-
beat 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.
