Why the study?
Older registries showed an increased incidence of significant findings during defibrillation testing at replacement, leaving its frequency of significant findings and safety uncertain.

DT during ICD replacement appears safe with low yield; leaves open whether routine testing should be abandoned pending larger studies.
Does intraoperative defibrillation testing provide clinically important information or cause complications in patients undergoing ICD generator replacement?
Intraoperative defibrillation testing during ICD generator replacement is safe but does not yield clinically important information, supporting the trend to abandon this practice.
