May lower defibrillation energy needs during ICD implantation; extends single-lead unipolar configurations for threshold optimization.
Does adding an inferior vena cava electrode to a single lead unipolar defibrillation system reduce the defibrillation threshold in patients undergoing ICD implantation?
Adding an inferior vena cava electrode to a single lead active CAN pectoral pulse generator significantly reduces the defibrillation threshold and impedance.
