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.
If you are healthy, your heart pumps blood to all the body's cells without causing undue stress on the vessels. Blood pressure is usually measured in either the right upper or left upper arm. A normal blood pressure is typically less than 120/80 mmHg (millimeters of mercury).f you are healthy, your heart pumps blood to all the body's cells without causing undue stress on the vessels.
