Which rhythm is characterized by electrical activity on monitor with no palpable pulse?

Pulseless electrical activity is when the monitor shows electrical rhythms, but there is no palpable pulse. The heart’s electrical system may be firing and you can see activity on the EKG, yet the mechanical pumping is insufficient or absent, so no blood is being pumped to produce a pulse. This distinguishes it from true ventricular fibrillation, where the ECG shows chaotic, disorganized activity rather than a recognizable rhythm, and from normal sinus rhythm or a junctional rhythm, where a pulse is present. In practice, PEA is managed with high-quality CPR and rapid treatment of reversible causes (the things that can stop the heart from effectively pumping), rather than immediate defibrillation, since there isn’t a shockable, organized rhythm to correct.
