What does the diastolic blood pressure number mean? The diastolic blood pressure number or the bottom number indicates the pressure in the arteries when the heart rests between beats. A normal diastolic blood pressure number is 80 or less. A diastolic blood pressure between 80 and 89 is normal but higher than ideal. A diastolic blood pressure number of 90 or higher, on repeated measurements, is considered to be hypertension or high blood pressure.
Blood pressure is measured as your systolic blood pressure over your diastolic blood pressure. Systolic blood pressure is the pressure put on your arteries when your heart beats and pumps blood. Diastolic blood pressure is the pressure put on your arteries between heartbeats, when your heart is resting.
