What is high blood pressure?
Blood pressure is the measurement of the pressure or force of blood pushing
against blood vessel walls. The heart pumps blood into the arteries (blood
vessels), which carry the blood throughout the body. High blood pressure, also
called hypertension, means the pressure in your arteries is above the normal
range. In most cases, no one knows what causes high blood pressure.
How is blood pressure recorded?
Blood pressure is written as two numbers, such as 118/72. The first number
is the systolic pressure. This is the pressure in the arteries when the heart
beats and fills them with blood. The second number is the diastolic pressure.
This is the pressure in the arteries when the heart rests between beats.
