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.

In a blood pressure reading, the diastolic pressure is typically the second number recorded. For example, with a blood pressure of 120/80 (120 over 80), the diastolic pressure is 80. By 80 is meant 80 mm Hg (millimeters of mercury). A diastolic murmur is a heart murmur heard during diastole, the time the heart relaxes. Diastolic came from the Greek diastole meaning a drawing apart. The term has been in use since the 16th century to denote the period of relaxation of the heart muscle.
