What causes a pulse deficit for an apical pulse?

A pulse deficit occurs when the apical pulse rate is slower than the radial pulse rate. This condition can be caused by several factors:

- Atrial fibrillation (AFib) is the most common cause of a pulse deficit. In AFib, the heart's upper chambers (atria) quiver instead of contracting normally, which can cause an irregular heartbeat and a pulse deficit.

- Premature atrial contractions (PACs) and premature ventricular contractions (PVCs) are extra heartbeats that can cause the heart to rate faster than normal temporarily, leading to a pulse deficit when they stop.

- Heart block is a condition that occurs when electrical signals from the heart's upper chambers (atria) are not properly conducted to the lower chambers (ventricles). This can result in a slow ventricular rate and a pulse deficit.

- Sick sinus syndrome (SSS) is a group of disorders characterized by abnormalities of the heart's natural pacemaker, leading to a slow or irregular heartbeat and potentially causing a pulse deficit.

- Valvular heart disease, such as mitral valve stenosis or aortic valve stenosis, can also lead to a pulse deficit.

If you experience a pulse deficit, discuss it with your doctor to determine the cause and undergo appropriate treatment.
