We report a case of early pace-maker malfunction associated with a collection of air which separates the anodal contact plate of a unipolar permanent generator from the underlying tissues. The air pocket resulted from a complication of the percutaneous technique used to introduce the electrocatheter through the subclavian vein. Loss of capture was attributed to a critical increase in impedance to current flow in the pacing system. The malfunction was corrected by simple non-invasive procedures at the patient's bedside. Air pocket can cause the loss of stimulation of the pace-maker.
我们报告一例早期起搏器故障，其与一团空气有关，该空气将单极永久起搏器的阳极接触板与下方组织分隔开来。气腔是经皮技术通过锁骨下静脉引入电导管的并发症所致。夺获失败归因于起搏系统中电流流动阻抗的显著增加。在患者床边通过简单的非侵入性操作纠正了故障。气腔可导致起搏器刺激丧失。
