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.
This is when the blood pressure is the greatest. The bottom number, or your diastolic reading, refers to the pressure in your arteries at all times, when the heart is resting in between heartbeats. The normal blood pressure is 120/80, although most people do not have blood pressure of exactly 120/80. Low blood pressure is much less common than high blood pressure. People with high blood pressure, or hypertension, are at risk for organ damage (kidney, and heart especially), in the long term.
