What does pulse deficit indicate?

Pulse deficit refers to the phenomenon where the number of pulses detected at the peripheral pulse points is fewer than the number of heartbeats observed through auscultation of the heart. This condition can indicate that not all heartbeats are strong enough to create a detectable pulse at the wrist or other peripheral locations.

When there is a pulse deficit, it usually suggests underlying cardiovascular issues, such as atrial fibrillation or other arrhythmias, where some heartbeats may be ineffective in generating adequate blood flow to produce a palpable pulse. Recognizing a pulse deficit is important in clinical practice, as it can help healthcare professionals assess the efficiency of the heart's pumping action and the overall health of the patient’s cardiovascular system.
