In pediatric arrest, amiodarone is considered in which scenario?

• A. VT/VF persists after defibrillation
• B. Asystole
• C. PEA
• D. Sinus tachycardia

Answer: (A)

In pediatric arrest, amiodarone is used for persistent or recurrent shockable rhythms after initial defibrillation. The goal in these cases is to stop ongoing VT or VF and prevent immediate recurrence, so after you deliver defibrillation and continue CPR, giving an antiarrhythmic helps stabilize the heart rhythm. Amiodarone works against a wide range of ventricular arrhythmias by prolonging repolarization and suppressing ectopic activity, which is why it’s chosen when VT or VF keeps returning despite shocks.

It’s not used for non‑shockable rhythms like asystole or pulseless electrical activity, where the focus is on high‑quality CPR and epinephrine rather than antiarrhythmic drugs. Sinus tachycardia isn’t an arrest rhythm and isn’t treated with amiodarone in this context. So the scenario where VT/VF persists after defibrillation is exactly when amiodarone is considered.
