Detailed explanation-1: -Systolic blood pressure (the first and higher number) measures pressure inside your arteries when the heart beats. Diastolic blood pressure (the second and lower number) measures the pressure inside the artery when the heart rests between beats.

Detailed explanation-2: -When your heart is at rest, between beats, your blood pressure falls. This is called diastolic pressure. Your blood pressure reading uses these two numbers.

Detailed explanation-3: -Systolic pressure is the maximum blood pressure during contraction of the ventricles; diastolic pressure is the minimum pressure recorded just prior to the next contraction. The blood pressure is usually written as the systolic pressure over the diastolic pressure (e.g., 120/80 mm Hg).

Detailed explanation-4: -Blood pressure readings are given in two numbers. The top number is the maximum pressure the heart exerts while beating (systolic pressure). The bottom number is the amount of pressure in the arteries between beats (diastolic pressure).

Detailed explanation-5: -The first number, called systolic blood pressure, measures the pressure in your arteries when your heart beats. The second number, called diastolic blood pressure, measures the pressure in your arteries when your heart rests between beats.
