Prolonged temporary pacing is associated with frequent complications. We describe a patient with aortic endocarditis and acquired tri-fascicular block in whom back-up pacing was indicated. Using a Seldinger technique via a subclavian approach, a permanent active-fixation lead was positioned in the right ventricle. The lead was tunnelled subcutaneously for 6 cm, and the proximal end was connected to a standard single chamber pulse generator. The procedure was well tolerated and over a period of four months there were no complications or infection. The PR interval subsequently reduced in duration to 200 ms and as no episodes of AV block had occurred, the lead was easily removed with retraction of the helix and gentle traction.
长期临时起搏与频繁的并发症相关。我们描述了一名患有主动脉心内膜炎和获得性三分支阻滞的患者，该患者需要备用起搏。通过锁骨下途径采用Seldinger技术，将一根永久性主动固定电极导线置于右心室。导线经皮下隧道潜行6厘米，近端连接到一个标准的单腔脉冲发生器。该操作耐受性良好，在四个月的时间里没有出现并发症或感染。随后PR间期缩短至200毫秒，由于未发生房室传导阻滞，通过旋出螺旋并轻柔牵拉，导线很容易被取出。
