Heartbeat 1

"Heartbeat 1" is a versatile term that can refer to anything from a medical diagnostic session to a technical server check or a creative project milestone.

The Mechanics:

So, what physically creates Heartbeat 1? It is not, as many assume, the contraction of the heart muscle itself. Instead, S1 is the sound of the atrioventricular (AV) valves slamming shut. Specifically, it is the closure of the mitral valve (left side) and the tricuspid valve (right side). As the ventricles contract, pressure inside them skyrockets, forcing these valves to snap closed to prevent blood from leaking backward into the atria. That snapping vibration is Heartbeat 1 . heartbeat 1
