Blood Pressure

Blood pressure is highest during systole when your heart contracts to force blood through the arteries. When the heart is at rest between beats, blood pressure falls to its lowest value, the diastolic pressure. A healthy person produces a systolic pressure of 90 and 120 mmHg and a diastolic pressure of 60- 80 mmHg. A normal blood pressure is 120 over 80.
