Transesophageal echocardiography was used for defining the unusual left atrial location of a malpositioned atrial pacemaker lead. This malpositioning occurred in a 75-year-old woman who had a small atrial septal aneurysm and a patent foramen ovale. Neither the precise location of the pacemaker lead tip nor the course of the lead was apparent by radiographic or transthoracic echocardiographic techniques. This report extends the potential utility of transesophageal echocardiography for the identification of malpositioned atrial pacemaker leads.
经食管超声心动图用于确定位置异常的心房起搏器导线在左心房的异常位置。这种位置异常发生在一名75岁的女性身上，她患有小型房间隔瘤和卵圆孔未闭。通过放射学或经胸超声心动图技术均无法明确起搏器导线尖端的精确位置或导线的走行。本报告扩展了经食管超声心动图在识别位置异常的心房起搏器导线方面的潜在应用价值。
