Systolic Diastolic Blood Pressure

Systolic pressure the pressure when your heart pushes blood out.

Systolic diastolic blood pressure. The blood pressure reading is measured in millimeters of mercury mmhg and is written as systolic pressure the force of the blood against the artery walls as your heart beats over diastolic. But even if your diastolic number is lower than 80 you can have elevated blood pressure if the systolic reading is 120 129. Learn what diastolic vs. 80 89 is stage 1 hypertension.

If the systolic blood pressure is lower than normal systolic hypotension is said to be present. Blood pressure is measured in millimetres of mercury mmhg and is given as 2 figures. Researchers are starting to give this condition more attention. Low diastolic blood pressure is when the lower number in your blood pressure reading falls below 60 mm hg.

A blood pressure reading will show the systolic blood pressure number first and diastolic blood pressure second. For example if your blood pressure is 140 over 90 or 140 90mmhg it means you have a systolic pressure of. 90 or more is stage 2 hypertension. A doctor will assess a person s blood pressure by considering both numbers.

Diastolic pressure occurs near the beginning of the cardiac cycle. In a study. It is the minimum pressure in the arteries when the pumping chambers of the heart ventricles fill with blood near the end of the cardiac cycle systolic pressure or peak pressure occurs when the ventricles contract. As the heart beats it pumps blood through a system of blood vessels which carry blood to every part.

If systolic hypotension is severe enough it can cause lightheadedness dizziness syncope or if it lasts long enough organ failure systolic hypotension can occur if the blood volume becomes too low as with severe dehydration or a major bleeding episode if the. We ll tell you why. If systolic blood pressure is elevated 140 mmhg with a normal diastolic blood pressure 90 mmhg it is called isolated systolic hypertension and may present a health concern. For those with heart valve regurgitation a change in its severity may be associated with a change in diastolic pressure.
