Supports anodal RV coil as default in ICD implantation; extends prior trials with quantified DFT reduction.
Does anodal RV coil polarity lower defibrillation thresholds compared to cathodal polarity in patients undergoing ICD implantation?
Anodal RV coil polarity significantly lowers defibrillation thresholds compared to cathodal polarity, suggesting it should be the default configuration during ICD implantation.
