검증된 단계별 안내1
Understand the basic anatomy of the heart, which includes the four chambers: two atria and two ventricles.
Learn about the electrical conduction system of the heart, which is responsible for initiating and regulating the heartbeat.
Identify the key components of the heart's conduction system: the Sinoatrial (SA) node, Atrioventricular (AV) node, Bundle of His, and Purkinje fibers.
Recognize that the Sinoatrial (SA) node is located in the right atrium and is known as the heart's natural pacemaker.
Understand that the SA node generates electrical impulses that initiate the heartbeat, causing the atria to contract and pushing blood into the ventricles.
