A 60-year-old ischaemic patient presented for routine cardiac resynchronization therapy (CRT)-D implantation. An investigational quadripolar left ventricular lead was placed in the posterolateral vein. Phrenic nerve stimulation (PNS) was observed, but it occurred during pacing from only one of the four electrodes. A lead with multiple pacing electrodes is a potential alternative to physical adjustment of the lead or discontinuing CRT when PNS occurs.
一位 60 岁的缺血性患者前来接受常规心脏再同步治疗（CRT-D）植入。一根研究用的四极左心室导联被放置在后外侧静脉中。观察到膈神经刺激（PNS），但仅在四个电极中的一个起搏时发生。当发生 PNS 时，具有多个起搏电极的导联是对导联进行物理调整或中断 CRT 的潜在替代方案。
