What is defined as a discrepancy between two pulse rates?

A discrepancy between two pulse rates is termed a pulse deficit. This condition is identified when there is a difference between the heart rate and the radial pulse rate. For example, if the heart is beating at a rate of 80 beats per minute but the radial pulse counts only 70 beats per minute, a pulse deficit of 10 exists. This phenomenon can occur in various cardiovascular conditions where some heartbeats do not generate a corresponding pulse that is palpable at the wrist. Recognizing pulse deficits is crucial in clinical practice, as it can indicate underlying health issues that may require further investigation.

In contrast, a pulse wave refers to the wave-like movement of blood through the arteries with each heartbeat, while pulse rhythm pertains to the pattern or regularity with which the heart beats. Pulsatile variation is not a standard term used in vital signs assessment and does not specifically address discrepancies in pulse rates. Understanding these distinctions allows for a more comprehensive interpretation of a patient’s cardiovascular health.
