11. The " systole " of a 1950 thesis by his student Pao Ming Pu. 12. Elevating Ca 2 + concentration to a high enough level results in cardiac arrest in systole . 13. Volumetric definition of the heart in systole was first described by Adolph Fick as cardiac output. 14. Annular velocities summarises the longitudinal contraction of the ventricle during systole , and elongation during diastole. 15. The cardiac cycle refers to a complete heartbeat which includes systole and diastole and the intervening pause. 16. "' Systole "'is the part of the cardiac cycle when the ventricles contract. 17. A reduced stroke volume may occur as a result of a failure of systole , diastole or both. 18. The time average of the first Korotkoff sound represents a reliable pressure marker of systole of the heart. 19. The name is derived from systole as an analogy to the regular pumping of blood by the heart. 20. Assuming a pulse of 72 beats per minutes, ventricular systole takes 0.3 seconds to complete.
