ABOUT BLOOD PRESSURE

♥
What are Systolic and Diastolic Pressure?
When the ventricles contract to pump blood out of the
heart, the blood pressure reaches its highest pressure
in the cycle. This is known as
systolic pressure
. The
lowest blood pressure in the cycle occurs when the
heart relaxes between heartbeats, and this is known as
diastolic pressure
.
The systolic pressure is the top number in your blood
pressure reading, and the diastolic is the bottom number.

What is a Normal
Blood Pressure?
The following charts illustrate the blood
pressure classification level established by
the World Health Organization (WHO) and
International Society of Hypertension (ISH)
in 1999.
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, consult your physician.
