Does a transvenous lead system with a coronary sinus electrode reduce defibrillation thresholds compared to an RV-thoracic patch system in survivors of cardiac arrest?
A transvenous defibrillation system utilizing a coronary sinus electrode significantly lowers defibrillation energy and voltage thresholds compared to an RV-thoracic patch system.
Bardy et al. (1990) studied this question.
