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.

Blood pressure has two components, systolic and diastolic pressure. Systolic pressure is the first number of a blood pressure measurement and reflects the pressure inside arteries when the heart pumps. Diastolic pressure, the second number, is the pressure when the heart relaxes between beats. High diastolic blood pressure -- also known as isolated diastolic hypertension or IDH -- is distinct from isolated systolic hypertension or elevation of both the systolic and diastolic blood pressure.
