Pulseless electrical activity is best described as which?

• A. An organized rhythm on ECG with a palpable pulse
• B. No electrical activity on ECG
• C. Rhythms organized on ECG but no palpable pulse
• D. Ventricular fibrillation

Answer: (C)

Pulseless electrical activity means there is organized electrical activity on the ECG but no palpable pulse. The heart’s electrical system is showing a structured rhythm, yet the mechanical action isn’t producing a detectable pulse or adequate perfusion. This distinguishes it from asystole, where there’s no electrical activity at all, and from ventricular fibrillation, which is chaotic and unorganized electrical activity. It also isn’t simply a normal organized rhythm with a pulse. In practice, recognizing an organized rhythm without a pulse means continuing CPR and addressing reversible causes rather than assuming no chance of return of spontaneous circulation.
