Comparative StudySuccessful implantation of cardiac defibrillators without induction of ventricular fibrillation using upper limit of vulnerability testing.
Conventionally, the implantable cardioverter-defibrillator (ICD) is tested at implantation by measurement of defibrillation threshold (DFT), which involves repeated induction of ventricular fibrillation (VF). We report our data on successful ICD implantation without VF induction using a modified upper limit of vulnerability (ULV) testing method, compared to standard DFT testing. ⋯ Successful ICD implantation can be safely performed with no or fewer episodes of VF induction using a modified ULV testing method.
