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.
What is the standard blood pressure
classification?
Irregular Heartbeat Detector
The blood pressure classification published by
World Health Organization (WHO) and
International Society of Hypertension (ISH) in
1999 is as follows:
An irregular heartbeat is detected when a heartbeat rhythm varies while the unit is
measuring the systolic and diastolic blood pressure.During each measurement,
this equipment records the heartbeat intervals and works out the standard deviation.
If the calculated value is larger than or equal to 15,the irregular heartbeat symbol
appears on the symbol when the measurement results are displayed.
Only a physician can tell your normal BP 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.
