When your heart beats, it contracts and pushes blood through the arteries to the rest of the body. This force creates pressure on the arteries. This is called systolic blood pressure. A normal systolic blood pressure is below 120.A systolic blood pressure of 120 to 139 means you have prehypertension, or borderline high blood pressure.Even people with prehypertension are at a higher risk of developing heart disease.his is called systolic blood pressure.

Systolic and Diastolic Blood Pressure. Systolic blood pressure (the top number) measures the amount of pressure that blood exerts on vessels while the heart is beating. Diastolic blood pressure (the bottom number) measures the pressure in your vessels between heartbeats. If systolic and diastolic blood pressures are too high, you have hypertension.
