Cardiac Cycle. in Physiology. Cardiac events appearing from the beginning of one heart beat to the beginning of next heart beat and repeating themselves successively. â¢ Cardiac cycle time (H.Rate = 75/min) : 0.8 sec. Systole: 0.27 sec. Diastole: 0.53 sec.
Using the principal that the fastest rate in the heart is the one that controls depolarization, ATP is performed by pacing faster than the arrhythmia cycle length, in this case 340ms, and then terminating the pacing train once it can be verified that the pacing stimuli are in control of depolarization or are capturing the myocardium.
