The historical preference for dual-coil implantable cardioverter defibrillator leads stems from high defibrillation thresholds associated with old device platforms. The high safety margins generated by contemporary devices have rendered the modest difference in defibrillation efficacy between single- and dual-coil leads clinically insignificant. Cohort data demonstrating worse lead extraction outcomes and higher all-cause mortality have brought the incremental utility of an superior vena cava coil into question. This article summarizes the current literature and re-evaluates the utility of dual-coil leads in the context of modern device technology.
历史上对双线圈植入式心律转复除颤器导线的偏好源于与旧设备平台相关的高除颤阈值。当代设备产生的高安全裕度使得单线圈和双线圈导线在除颤效果上的适度差异在临床上变得微不足道。队列数据显示导线拔除结果更差且全因死亡率更高，这使得上腔静脉线圈的增量效用受到质疑。本文总结了当前的文献，并在现代设备技术的背景下重新评估了双线圈导线的效用。
