The bottom number, called the diastolic pressure, is the measurement as the heart relaxes between beats. Normal blood pressure is a systolic pressure of less than 120 millimeters of mercury (mm Hg) and a diastolic pressure of less than 80 mm Hg, or 120/80 mm Hg, according to the American Heart Association (AHA).Having a blood pressure greater than 140/90 mm Hg is considered high blood pressure or hypertension.A blood pressure level between normal and hypertension, is called prehypertension, meaning it is higher than normal, but not high enough to be considered hypertension.aving a blood pressure greater than 140/90 mm Hg is considered high blood pressure or hypertension. A blood pressure level between normal and hypertension, is called prehypertension, meaning it is higher than normal, but not high enough to be considered hypertension.
Normal blood pressure is below 120/80; blood pressure between 120/80 and 139/89 is called pre-hypertension, and a blood pressure of 140/90 or above is considered high while a systolic blood pressure of about 90 to 100 is considered low blood pressure.
