Hypertension, referred to as high blood pressure, is a condition in which the arteries have persistently elevated blood pressure. The normal level for blood pressure is below 120/80, where 120 represent the systolic measurements and 80 represent the diastolic measurement. Blood pressure of 140/90 or above is considered hypertension.
