Low failure rates may reassure on routine ICD testing; leaves open whether NYHA class should guide selective protocols.
What is the rate of failing to achieve a 10 J safety margin during initial defibrillation conversion testing with modern dual-chamber ICD systems?
Modern dual-chamber ICD systems almost always meet successful defibrillation conversion criteria with the first configuration tested, requiring system revisions in only 3.9% of patients.
Day et al. (2008) studied this question.
