Cardiac cycle is the sequence of events that occurs in the heart during one full heart beat. These events comprise contraction (systole) and relaxation (diastole) of the chambers of the heart, associated with opening and closing of the heart valves. At a resting heart rate, the human cardiac cycle lasts approximately 0.85 second, ie, 0.8 seconds.
