In a child with VT with a pulse who becomes unstable, what is the recommended immediate treatment?

• A. Defibrillate immediately at 2 J/kg
• B. Continue CPR without defibrillation
• C. Administer immediate epinephrine only
• D. Synchronized cardioversion at 0.5–1 J/kg (and escalate as needed)

Answer: (D)

When a child has ventricular tachycardia with a pulse but becomes unstable, the priority is to restore a stable rhythm with synchronized cardioversion. The rhythm is shockable, but because a pulse is present you synchronize the shock to the QRS complex to avoid delivering a shock that could worsen the rhythm. Start with a energy of 0.5 to 1 joule per kilogram, and if needed, escalate to 2 J/kg for subsequent shocks. After cardioversion, reassess the patient and repeat shocks if instability persists, then consider antiarrhythmic options as guidelines suggest. Defibrillating unsynchronized would be used if there were no pulse (pulseless VT or VF), which isn’t the scenario here. Continuing CPR without delivering a synchronized shock isn’t appropriate when a shockable rhythm with a pulse is present. Administering epinephrine alone does not promptly correct unstable VT with a pulse and is not the first-line treatment in this situation.
