心脏结节病患者在整个右心室（RV）表现出低R波振幅。为了排除故障，在冠状静脉中植入了左心室（LV）电极导线。除颤电极导线的起搏/感知端子连接至除颤器的LV：IS-1。相反，LV电极导线连接到RV：IS-1。诱导室颤成功终止，无任何感知不足。
A patient with cardiac sarcoidosis showed low R-wave amplitude in the entire right ventricle (RV). To troubleshoot this, a left ventricular (LV) lead was implanted in the coronary vein. The pace/sense terminal of the defibrillation lead was connected to LV:IS-1 of the defibrillator. Conversely, the LV lead was connected to RV:IS-1. Induced ventricular fibrillation was successfully terminated without any undersensing.
