Verified step by step guidance

Understand the components of the cardiac conduction system, which is responsible for initiating and coordinating the heartbeat.

Identify the key structures involved in the cardiac conduction system: the Sinoatrial (SA) node, Atrioventricular (AV) node, Bundle of His, bundle branches, and Purkinje fibers.

Recognize that the Sinoatrial (SA) node is known as the heart's natural pacemaker, initiating the electrical impulse.

Acknowledge that the Atrioventricular (AV) node receives the impulse from the SA node and relays it to the ventricles.

Note that the Mitral valve is a part of the heart's structure, specifically a valve between the left atrium and left ventricle, and not involved in the conduction of electrical impulses.
