What does a pulse deficit indicate?

A pulse deficit indicates that there is a difference in the heart rate between the apical pulse and the radial pulse, which is typically assessed by taking both pulses simultaneously. When there is a pulse deficit, it specifically means that the radial pulse is slower compared to the apical pulse. This often suggests that not all heartbeats are effectively reaching the periphery, which can occur in situations such as arrhythmias or other cardiovascular issues.

In this context, the apical pulse is taken at the apex of the heart using a stethoscope, while the radial pulse is taken at the wrist. If the apical pulse is higher than the radial pulse, the difference is termed a "pulse deficit," and this generally indicates a problem with the heart's ability to pump blood efficiently. Understanding this relationship is crucial in clinical assessments, as it helps in diagnosing potential cardiac issues.
