What rhythms are considered non-shockable in CPR?

• A. Ventricular fibrillation and pulseless VT.
• B. Asystole and pulseless electrical activity (PEA).
• C. Ventricular tachycardia with a pulse.
• D. Normal sinus rhythm.

Answer: (B)

In CPR, you treat some rhythms with a shock and others without. Non-shockable rhythms are those where delivering a shock isn’t indicated or effective. The two non-shockable rhythms are asystole, where there’s no electrical activity at all (a flat line), and pulseless electrical activity, where there is electrical activity on the monitor but no resulting heartbeat or pulse. In these cases, the focus is on high-quality CPR and addressing reversible causes, with defibrillation used only when the rhythm becomes shockable. The other options describe rhythms that are either shockable (ventricular fibrillation and pulseless VT) or a normal rhythm with a pulse, which isn’t an arrest rhythm.
