When the electrical conduction of the heart?

The electrical conduction of the heart refers to the system that coordinates the heartbeat through electrical impulses. It begins at the sinoatrial (SA) node, which acts as the natural pacemaker, generating impulses that spread through the atria, causing them to contract. The impulses then travel to the atrioventricular (AV) node and down the bundle of His, branching into the right and left bundle branches, leading to the contraction of the ventricles. This organized conduction ensures effective blood pumping and rhythmic heartbeats.
