Overview

DT may warrant consideration in complex or upgrade ICD cases; leaves open whether routine testing improves outcomes.

Structured PICO

Does intraoperative defibrillation testing identify ineffective shocks and remain safe in patients undergoing ICD procedures?

P
Population
4,572 consecutive patients undergoing any implantable cardioverter defibrillator (ICD) intervention
I
Intervention
Intraoperative defibrillation testing (DT)
O
Outcome
Primary DT effectiveness and DT-associated complicationssurrogate

A 4.2% initial failure rate of intraoperative defibrillation testing suggests it should not be universally abandoned, particularly for complex, non-standard, or upgrade ICD procedures.
