Systole information

Systole (/ˈsɪstəli/ SIST-ə-lee) is the part of the cardiac cycle during which some chambers of the heart contract after refilling with blood. The term...

Atrial systole lasts approximately 100 ms and ends prior to ventricular systole, as the atrial muscle returns to diastole. Ventricular systole follows...
