diastolic pressure

The diastolic pressure - The lowest level of blood pressure measured in the main arteries. Diastolic pressure is the pressure between heartbeats, when the ventricles (the lower chambers of the heart) are relaxed and filling with blood. Systolic pressure, the highest level of blood pressure in the main arteries, occurs when the ventricles of the heart contract.

The normal range of blood pressure varies with age and between individuals, but a young adult usually has a diastolic pressure of about 80 mmHg (mm of mercury) and a systolic pressure of about 120 mmHg. A persistently high diastolic pressure occurs in most cases of hypertension.
