May support single-lead pectoral defibrillators; leaves open randomized confirmation of long-term outcomes.
Unipolar pectoral transvenous defibrillation systems provide excellent efficacy and survival, virtually eliminating the morbidity of older epicardial systems, though inappropriate shocks remain a challenge.
Reddy et al. (1997) conducted a review in Sudden cardiac death / Arrhythmias. Single lead pectoral defibrillation systems vs. Epicardial systems was evaluated on Overall survival. Single lead pectoral defibrillation systems are 99% effective at eliminating sudden death, with an overall survival of 94.4% at 18 months.
