What is a time of cardiac cycle?
Cardiac events appearing from the beginning of one heart beat to the beginning of next heart beat and repeating themselves successively.
? Cardiac cycle time (H.Rate = 75/min) : 0.8 sec
Systole : 0.27 sec
Diastole: 0.53 sec
? Systole : Contraction and emptying
Muscle stimulated by action potential and contracting
? Diastole : Relaxation and filling
Muscle reestablishing Na+/K+/Ca++ gradient and is relaxing
?Atria and ventricles go through separate cycles of
systole and diastole.
?Atria contract prior to the ventricular contraction i.e.
when atria contract ventricles relax and vice versa.
? Each ventricle expels same volume of blood/beat.
