Key result
Revising a subcutaneous implantable cardioverter defibrillator to an intermuscular pocket prevents device migration and provides stable sensing vectors to avoid inappropriate shocks.
Why the study?
Does revision of S-ICD to an intermuscular pocket prevent inappropriate shocks and device migration?
Does revision of S-ICD to an intermuscular pocket prevent inappropriate shocks and device migration?
Placing an S-ICD in an intermuscular pocket may prevent device migration and inappropriate shocks by providing stable sensing vectors.
May favor intermuscular S-ICD pockets for stability; hypothesis-generating and requires prospective confirmation.
Sensing and defibrillation threshold for a S-ICD are impacted by positioning at implant or revision. The intermuscular pocket prevents device migration and provides appropriate, stable sensing vectors.
