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 Mean Arterial Pressure is an approximation for the time-weighted average of blood pressure values in large system arteries during the cardiac cycle.  Diastolic Blood Pressure is the minimum blood pressure measured in large systemic arteries. The lowest value occurs just before the start of every ventricular systole.
