The first sound of a heartbeat is caused by the closing of the atrioventricular valves (mitral and tricuspid valves) in the heart and marks the beginning of ventricular systole, where the ventricles contract to pump blood. This sound is known as the "lub" sound of the heartbeat.

What is the relationship between a heartbeat a pulse rate?
A heartbeat refers to the sound produced by the contraction and relaxation of the heart muscle, while the pulse rate is the number of times the arterial walls expand and contract in response to the pressure of blood being pumped by the heart. Each heartbeat results in a pulse, so the pulse rate is directly related to the heartbeat.

The second heart sound, "dub," is heard when the relaxation of the ventricles allows the semilunar valves to close.

What are terms for heart beats?
Pulse (pulse = to beat) or Complete Cardiac Cycle (beginning of one heartbeat until the beginning of the next) are two medical term for "heartbeat". Listen to your heartbeat and you might distinguish two sounds. The first sound is the closing of the upper atrioventicular valves. The second sound is the closing of the semilunar valves. This is the pushing of the blood out of the heart. Between beats, the heart is filling with blood and preparing for another push or pulse.
