In synchronized cardioversion for pediatric tachyarrhythmias, to what energy should the initial shock be escalated if needed?

• A. 4 J/kg
• B. 1 J/kg
• C. 0.5 J/kg
• D. 2 J/kg

Answer: (D)

Energy dosing for synchronized cardioversion in pediatric tachyarrhythmias is weight-based and performed in steps. The initial synchronized shock is given at about 0.5 to 1 J/kg. If that does not convert the rhythm, the next, higher-energy shock is delivered at 2 J/kg. If still unsuccessful, you would escalate to 4 J/kg. This progression balances the need to reliably terminate the tachyarrhythmia with the goal of minimizing myocardial injury. So the escalation target after the initial dose is 2 J/kg.
