The normal heartbeat begins as an electrical impulse in the sino-atrial node (or SA node). The SA node is called the pacemaker of the heart. It is located in the R atrium, just below the entrance of the superior vena cava.
Sinoatrial node; located in the right atrium.

Paroxysmal Atrial Tachycardia (PAT)
the action potentials associated with heartbeat regulation originate in the SA node, I believe it is in somewhere in the wall of the right atrium of the heart
In the Sinoatrial Node
Bundle of His .
One compound word that begins with "hear" is "heartbeat."
Each heartbeat begins with an action potential generated at the sinoatrial node or simple call the SAnode.
The sinoatrial(SA) node located in the right atrium.
Pacemaker (sinoatrial node)
The SA node begins the heartbeat and is sometimes referred to as the heart's pacemaker. The AV node are where the electrical impulses are delayed for 0.1 second before spreading to both ventricles and causing them to contract.
Right Atrium chamber wall.
The electrocardiogram indicates when each heartbeat begins, triggering the cuffs to be mechanically deflated. As each heartbeat ends, the cuffs are mechanically inflated
