What Is Blood Pressure Diastolic

Systolic pressure the pressure when your heart pushes blood out.

What is blood pressure diastolic. It measures the force of blood against your artery walls as your heart relaxes and the ventricles are allowed to refill with blood. After the heart is finished contracting the cardiac ventricles relax momentarily so that they can be refilled with blood in preparation for the next contraction. A normal diastolic blood pressure is lower than 80. The diastolic blood pressure is the pressure the blood exerts within the arteries in between heartbeats that is when the heart is not actively ejecting blood into the arteries.

Diastolic pressure the pressure when your heart rests between beats. But even if your diastolic number is lower than 80 you can have elevated blood pressure if the systolic reading is 120 129. For example if your blood pressure is 140 over 90 or 140 90mmhg it means you have a systolic pressure of. Blood pressure is measured in millimetres of mercury mmhg and is given as 2 figures.

Blood pressure bp is the pressure of circulating blood on the walls of blood vessels most of this pressure is due to work done by the heart by pumping blood through the circulatory system used without further specification blood pressure usually refers to the pressure in large arteries of the systemic circulation blood pressure is usually expressed in terms of the systolic pressure. This is the lower number which shows the pressure that the blood applies to the artery walls when the heart rests between beats. Researchers are starting to give this condition more attention. We ll tell you why.

Your diastolic blood pressure is the bottom number on your reading. This is the time when the heart fills with blood and gets oxygen.
