Pulse is defined physiologically as the rhythmic expansion and subsequent recoil of an artery wall, detectable by palpation at various peripheral sites. This palpable wave is generated by the pumping action of the circulatory system and reflects the systemic blood pressure and cardiac output. Measuring pulse rate provides essential diagnostic information regarding the frequency of heartbeats and can offer qualitative data on the circulatory efficiency. Variations in pulse quality or rate are key indicators that may suggest underlying cardiac, vascular, or systemic imbalances, requiring careful objective analysis of physiological status.
