Solution
The normal pacemaker of the heart is the SA node.
Here's why:
-
The heart's electrical system controls the rate and rhythm of the heartbeat.
-
The Sinoatrial (SA) node, located in the right atrium of the heart, is responsible for initiating each heartbeat. It does this by producing electrical impulses that spread through the walls of the atria, causing them to contract and pump blood into the ventricles.
-
The electrical impulses then reach the Atrioventricular
