If the pressure is high during the pumping phase (systole), then the first number recorded with a blood pressure reading (the systolic pressure) will be high.
High blood pressure means that there is higher than normal pressure inside the arteries either during systole (when the heart contracts and pumps blood through the body), or during diastole (when the heart relaxes and fills with blood). This recording represents how high the mercury column is raised by the pressure of the blood. It occurs when the heart relaxes and fills with blood.Įach time the heart beats, it pumps blood into the arteries, resulting in the highest blood pressure, the systolic pressure, as the heart contracts, and the lowest blood pressure, the diastolic pressure, as the heart relaxes.īoth the systolic and diastolic pressures are recorded as "mm Hg" (millimeters of mercury). The lower number, or diastolic pressure, refers to the lowest pressure inside the artery. It occurs when the heart contracts and pumps blood into the body.
