Cardiac Electrical Conduction System 01 | Electrical Circuit of Heart 01 The electrical system of the heart is like the body's own natural power grid. It's responsible for coordinating the heartbeat and ensuring that the heart pumps blood efficiently. The process begins with the sinoatrial (SA) node, often called the "natural pacemaker." This node generates electrical impulses, initiating each heartbeat. The impulses then travel through the atria, causing them to contract and pump blood into the ventricles. Next, the impulses reach the atrioventricular (AV) node, which acts as a kind of relay station. The AV node briefly delays the electrical signal, allowing the ventricles to fill with blood before contracting. This delay ensures an organized and effective pumping action. Finally, the electrical impulses travel down specialized pathways called the bundle of His and Purkinje fibers, stimulating the ventricles to contract and pump blood to the lungs and the rest of the body. In essence, this intricate electrical system ensures that the heart beats in a coordinated and rhythmic manner, maintaining the vital circulation of blood throughout the body.
