Opening and closing of valves. The cycle is broken down into three stages: This cycle consists of a diastole phase and a systole phase.
Describes sequence of events that occur in the heart over one beat.
10+ Cardiac Cycle Diagram. Cardiac cycle the cardiac muscles of the heart contract and relax in a rhythmic cycle. At the beginning of the cardiac cycle, both atria and ventricles are in diastole. The cardiac cycle describes the series of events that take place in the heart over the duration of a throughout the cycle, aortic pressure remains quite high as muscle and elastic fibres in the artery. The cardiac cycle begins with the atrium and ventricle in a relaxed state.
