Conduction System of the Heart and Cardiac Cycle
The conduction system of the heart generates electrical impulses that regulate heartbeats. Beginning with the sinoatrial (SA) node, these impulses travel through the atrioventricular (AV) node, bundle of His, and Purkinje fibers, causing the heart’s chambers to contract in a coordinated manner. This process, known as the cardiac cycle, comprises atrial and ventricular systole, where chambers contract, and diastole, where they relax and fill with blood. Together, the conduction system and cardiac cycle ensure rhythmic heart function and efficient blood circulation throughout the body.
Anatomy and Functions of Heart’s Electrical System
The heart electrical system controls the heartbeat by sending electrical signals through the heart, coordinating the contraction and relaxation of the heart muscles. The conduction system of the heart controls the electrical impulses that coordinate the heartbeat.
Understanding the heart electrical system pathways and the conduction system of the heart flowchart helps us comprehend how the heart beats and maintains a regular rhythm. In this article, we will cover the conduction system of the heart in detail.
