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.

The compound word that begins with hear is hearsay.
Each heartbeat begins with an action potential generated at the sinoatrial node or simple call the SAnode.
Pacemaker (sinoatrial node)
The sinoatrial(SA) node located in the right atrium.
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.
Action potentials associated with heartbeat regulation originate in the sinoatrial (SA) node, often referred to as the heart's natural pacemaker. The SA node generates electrical impulses that spread through the heart, coordinating the contraction of the atria and the ventricles. This rhythmic action potential initiation in the SA node is crucial for maintaining a regular heartbeat.
The electrocardiogram indicates when each heartbeat begins, triggering the cuffs to be mechanically deflated. As each heartbeat ends, the cuffs are mechanically inflated

Heartache, heartbeat, heartbreak, heartburn and heartthrob are words. They begin with the letters heart.
