To discuss:
The different phases of cardiac cycle; chambers depolarize and repolarize; contraction and relaxation and its corresponding ECG waves; heart sounds, blood moves in or out of atria; blood volume; and pressure changes in left and right ventricles and aorta.
Introduction:
The cardiac cycle is a rhythm that is termed by the duration of one heartbeat to the other beat. A typical heartbeat consists of two stages namely diastole and systole. Heart muscles to relax and its chambers to be filled with blood is termed as diastole, and this beat makes the “lub” sound. Contraction of heart muscles and ejection of blood by the chambers of the heart are termed as systole, and this makes the “dub” sound of the heart. Cardiac cycle is illustrated diagrammatically by “Dr.CarlJ.Wiggers,” and henceforth the cardiac cycle is named as Wiggers diagram.
