What is palpable pulse caused by?

A palpable pulse is caused by the rhythmic expansion and contraction of arteries as blood is pumped through them by the heart. This occurs during ventricular systole when the heart contracts and forces blood into the arteries, creating pressure waves that can be felt at various points on the body, such as the wrist or neck. Factors such as heart rate, stroke volume, and vascular resistance can influence the strength and characteristics of the palpable pulse.
