Cardiac Cycle The cardiac cycle is a normal activity of the human heart and is regulated automatically by the nodal tissues the sinoatrial node (sa node) and atrioventricular node (av node). the variation in the cardiac cycle results in an increase or decrease in cardiac output. the occurrence of a cardiac cycle is illustrated by the heartbeat rate, which. 19.3 cardiac cycle – anatomy & physiology.

The Cardiac Cycle And The Regulation Of Cardiac Activity Physiology, cardiac cycle statpearls. Cardiac cycle phases: definition, systole and diastole heart. Cardiac cycle cardiac cycle. The period of time that begins with contraction of the atria and ends with ventricular relaxation is known as the cardiac cycle (figure 19.4.1 19.4. 1 ). the period of contraction that the heart undergoes while it pumps blood into circulation is called systole. the period of relaxation that occurs as the chambers fill with blood is called diastole.

Relate the heart sounds to the events of the cardiac cycle. the period from the start of one heartbeat to the start of the next, including both systole and diastole phases is known as the cardiac cycle. the contraction phase of the heart, during which blood is pumped into circulation is called systole. the relaxation phase of the heart, during.
