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.
1 Systolic pressure denotes the maximum pressure along the blood vessels when the heart is contracting, whereas diastolic pressure indicates the minimum pressure along the blood vessels when the heart is relaxed. 2  There are four chambers of the heart: right and left atrium and right and left ventricles.
