Duration of a cardiac cycle

WebThe cardiac cycle is the time period comprising all the events from one heart contraction to the start of the next heart contraction. Each of these cycles starts with 1. the depolarization of the SA node which is then followed by the 2. atrial systole [0 seconds], 3. then ventricular systole [0 seconds], WebThe total duration of the cardiac cycle, including systole and diastole, is the reciprocal of the heart rate. For example, if heart rate is 72 beats/min, the duration of the cardiac cycle is 1/ 72 beats/ min about 0.0139 minutes per beat, or 0.8 second per beat.
