Clinical predictors of atrial defibrillation thresholds with a dual-coil, active pectoral lead system

Clinical parameters are of limited use in predicting atrial DFT with a dual-coil, active pectoral ICD lead system. Because the RV→SVC+CAN shocking pathway provides reliable atrial and ventricular defibrillation, this configuration should be preferred for combined atrial and ventricular ICDs.
