Cardiac Cycle Definition
The cardiac cycle is the complete sequence of events in a single heartbeat, including ventricular contraction and relaxation, ensuring blood circulation. It is controlled by electrical signals from the SA and AV nodes.
Cardiac Cycle- Phases, Diagram, and Physiology of the Cardiac Cycle
The cardiac cycle is a sequential event in the heart that is cyclically repeated. The cardiac cycle diagram shows the cardiac cycle phases consisting of systole and diastole of both the atria and ventricles. The cardiac cycle class 11 is an important concept that is also studied in higher classes.
It is regulated by electrical signals from the sinoatrial (SA) node and atrioventricular (AV) node, which ensures the circulation of oxygenated blood throughout the body. The heart beats 72 times per minute, that is many cardiac cycles are performed per minute. In this article, we will cover the cardiac cycle – steps, diagram, and physiology of the cardiac cycle.
