Hypertension is a persistent elevation of the blood pressure where the systolic pressure (pressure when the heart contracts) is greater than 140 mm.Hg and a diastolic pressure (pressure when the heart relaxes) is above 90 mm.Hg. However, other factors have to be taken into consideration, especially when evaluating an increased systolic pressure before diagnosing a patient with high blood pressure.
