What is the order of "normal" electrical conduction of the heart?

Question

Quizplus · Accepted Answer

The normal electrical conduction of the heart starts with the sinoatrial (SA) node, which is the natural pacemaker of the heart. From there, the impulse travels to the atrioventricular (AV) node, which acts as a gatekeeper, delaying the impulse slightly to allow for ventricular filling. The impulse then travels down the Bundle of His, which divides into the left and right bundle branches and finally, the Purkinje fibers, which spread the electrical signal throughout the ventricles, causing them to contract. This order ensures efficient and synchronized contraction of the heart muscles.
