CV Physiology | Hypertension - Introduction

Arterial blood pressure is \\"normal\\" when the systolic pressure is 90-119 mmHg and the diastolic pressure is 60-79 mmHg. Blood pressures <90/60 mmHg are considered abnormally low (hypotension). When the arterial pressure is ≥120/80 mmHg, a person is said to have \\"elevated\\" pressure or hypertension. Mean arterial pressure is also elevated in hypertension, but it is not usually measured in people. In past years, the diastolic value was emphasized in assessing hypertension. However, elevatio
