In the VAD protocol, which rhythm is treated as a shock patient?

• A. Sinus Tachycardia
• B. V-Fib
• C. Atrial Fibrillation
• D. Normal Sinus Rhythm

Answer: (B)

The main idea is identifying a rhythm that requires defibrillation. A shockable rhythm is one where the heart’s electrical activity is chaotic and there’s no effective heartbeat, so a defibrillator shock is used to reset the rhythm and restore organized pumping. Ventricular fibrillation fits this perfectly: the ventricles quiver without coordinated contraction, producing no usable output, so immediate defibrillation is indicated to restart a viable rhythm. In contrast, sinus tachycardia and normal sinus rhythm are organized and usually indicate the heart is pumping effectively, so they aren’t treated with shocks. Atrial fibrillation is irregular, but it’s not typically shocked unless there’s no pulse; with a pulse, it’s managed medically rather than with immediate defibrillation. So the rhythm treated as a shock patient is ventricular fibrillation.
