Implication
Supports deferring routine DFT testing at ICD implantation; leaves open the need for randomized confirmation.

Routine defibrillation threshold (DFT) testing at time of ICD implant

Routine DFT testing during ICD implantation provides a marginal and non-significant 5-year survival benefit compared to no testing in a decision analysis model.
