Blood pressure is measured in two values: systolic, upper number, (the pressure when the heart beats) and diastolic, lower number. (the pressure when the heart rests between beats). A normal blood pressure reading is around 120/80 mmHg. Medical professionals diagnose hypertension when they consistently measure blood pressure at 140/90 mmHg or higher.
