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
classication?
Irregular Heartbeat Detector
Below illustrates the blood pressure
classication mode by World Health Organization
(WHO) and International Society of Hypertension
(ISH) in 1999.
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.
Caution: Only a physician can tell you your normal blood pressure range and the
point at which you are at risk. Consult your physician to obtain these values.
If the measurements taken with these products fall outside the range.
