What is the difference between systolic and diastolic pressure?

The difference between the systolic and the diastolic pressure is the pulse

Explanation:

Systolic blood pressure is the top number of the maximum pressure your heart exerts while beating (systolic pressure),

and the bottom number is the amount of pressure in your arteries between beats (diastolic pressure).

The numeric difference between your systolic and diastolic blood pressure is called your pulse pressure.

Hence systolic - diastolic = pulse

Pulse pressure

Explanation:

Blood pressure readings are given in two numbers, upper and lower limit.

- The upper limit is the maximum pressure your heart exerts while beating, also called systolic pressure.

- The lower is the amount of pressure in your arteries between beats, also called diastolic pressure.

- The numerical difference between systolic and diastolic pressure is called the pulse pressure.

- For example, if your resting blood pressure is 120/80 millimeters of mercury (mm Hg).

systolic pressure = 120 mm Hg

diastolic pressure = 80 mm Hg

Pulse pressure = 120 - 80 = 40 mm Hg
