As the heart beats, it circulates blood through pulmonary and systemic circuits of the body. There are two phases of the cardiac cycle. In the diastole phase, the heart ventricles are relaxed and the heart fills with blood. In the systole phase, the ventricles contract and pump blood out of the heart and to arteries.

The electrical and mechanical events that occur from the beginning of one heartbeat at the beginning of the next heartbeat is called cardiac cycle.
The first electrical event in the cardiac cycle is the initiation of a spontaneous action potential in the sinus node (SA node) which is located in the superior lateral wall of the right atrium near the opening of superior vena cava.
There is a delay of.01 second for the current to pass from the atria to the ventricles and it allows the atria to contract completion and pump all the blood to ventricles before ventricle contraction begins.
