What are systolic pressure and diastolic pressure?
When ventricles contract and pump blood out
of the heart, the blood pressure reaches its
maximum value in the cycle, which is called
systolic pressure. When the ventricles relax, the
blood pressure reaches its minimum value in
the cycle, which is called diastolic pressure.
What is the standard blood pressure classification
The blood pressure classification published by World Health Organization (WHO) and
International Society of Hypertension (ISH) in 1999 is as follows:
CAUTION

range.Please contact a physician if your
measuring result falls out of the range.
