May aid pre-procedural risk stratification for high DFT; leaves open whether targeted lead or waveform adjustments improve outcomes in these patients.
What are the independent clinical and echocardiographic predictors of a high defibrillation threshold in patients undergoing ICD implantation with a transvenous dual-coil lead?
Atrial fibrillation, hypertension, and interventricular septal hypertrophy (>12 mm) are independent predictors of high defibrillation thresholds during ICD implantation, which may help identify patients at higher risk for testing complications.
