noun

Physiology
The phase of the heartbeat when the heart muscle contracts and pumps blood from the chambers into the arteries. Often contrasted with diastole.
More example sentences
  • The passive, elastic recoil between systoles maintains the blood pressure, smooths the flow of blood, and forces blood through the coronary arteries while the ventricles are filling.
  • The reflected wave returns to the aorta during systole rather than diastole, increasing systolic work even more and reducing diastolic pressure, on which coronary flow depends.
  • A newer classification scheme for heart failure is based not on left or right side failure but rather on whether the failure occurs during systole or diastole.
