In Pediatric Unstable Polymorphic VT, what is the defibrillation energy sequence?

• A. 1 J/kg, 2 J/kg, 4 J/kg
• B. 2 J/kg, 6 J/kg, 12 J/kg
• C. 2 J/kg, 4 J/kg, 10 J/kg
• D. 5 J/kg, 10 J/kg, 15 J/kg

Answer: (A)

In pediatric defibrillation for unstable polymorphic VT, you use weight-based escalating shocks to balance safety with effectiveness. Start with a very low energy suitable for the smallest patients, then increase in steps if the rhythm does not convert. The sequence 1 J/kg first, then 2 J/kg, and finally 4 J/kg reflects this cautious, doubling pattern: it minimizes potential myocardial injury from high initial energy while giving each subsequent shock a higher chance to interrupt the malignant rhythm. This approach aligns with the principle of using the lowest effective dose and then stepping up as needed.
