One complete heartbeat is known as a/an

Question

Quizplus · Accepted Answer

A cardiac cycle is the complete sequence of events that occurs during one heartbeat, including both systole and diastole. A single heartbeat involves the contraction and relaxation of both the atria and ventricles, which results in the flow of blood through the heart and into the circulatory system. While an ECG cycle and sinus rhythm are related to heart function, they do not specifically refer to a complete heartbeat. Ventricular contraction is only one part of the cardiac cycle, and does not encompass the entire cycle.
