Correct answer: E — Start CPR and defibrillate as soon as the defibrillator is ready

Commotio cordis presents as sudden VF after chest impact, and survival depends on immediate CPR and early defibrillation. A precordial thump is not a substitute for prompt defibrillation when a defibrillator is available. Glucose testing and transport must not delay resuscitation. The pearl is that public-access defibrillation is particularly important at sports venues.
