Forceful extraction of an Elema unipolar endocardial pacing electrode caused accidental detachment of the electrode tip. The tip migrated from the jugular vein into the central venous circulation and after some delay finally passes during the night into a pulmonary artery branch. Transient pleural irritation was the only sequel.
用力拔出Elema单极心内膜起搏电极导致电极头意外脱落。电极头从颈静脉移入中心静脉循环，经过一段时间延迟后，最终在夜间进入一支肺动脉分支。唯一的后续情况是短暂的胸膜刺激。
