Early defibrillation is critical to survival in any patient with a cardiac arrest.Electrophysiologists who implant ICDs(implantable cardioverter defi-brillators)test them by fi brillating the patient followed by immediate defibrillation.This emphasizes the point that early defibrillation results in survival of these patients;CPR is done only if there is a delay in obtaining the defi brillator or if the ICD is not working.
