摘　　要：目的比较经胸二维与三维超声心动图在定位人工心脏起搏器电极导线位置的应用价值。方法采用Philips公司Sonos7500型超声心动图检查仪,配备实时三维超声动态成像技术(X4矩阵探头)。对28例单腔或双腔人工心脏起搏器安置术后起搏器电极导线在心腔内的行走路径、导线顶端嵌入位置以及起搏器电极与三尖瓣及瓣下结构的关系等进行观察。运用实时三维成像(实时显像Live-3D、全容积显像Full volume)及三维彩色血流显像(RT-3DCFI)3种显像方式。结果二维超声心动图能显示其中26例(检出率92.9%)患者的电极导线及21例(检出率75.0%)患者导线顶端的位置,余5例患者导线顶端的位置经实时三维超声确诊。除此之外,另1例AAI及1例DDD起搏患者由于肺气肿二维图像质量欠佳影响三维显像,2种方法均无法观察到右房内起搏电极导线位置。本组28例单腔或双腔心脏起搏器患者采用实时三维成像技术后全部检出(100%)。结论实时三维超声较二维超声能更直观、准确、实时地显示起搏电极导线及导线顶端在心腔内的位置、周邻关系及所致三尖瓣活动的改变。Objective To compare the practical value in identifying the position of electrode conduct line of antifi cial cardic pacemaker by 2D and 3D thoracic ultrasonic cardiogram. Methods The passage of electrode line in the cavi ty of heart and the place where the top of the line was buried and the relation between electrode and tricuspidalis of 28 cases using single cavity or double cavities artificial pacemakers were observed. There are three types of imaging： live 3D movable imaging （live 3D imaging, full volume imaging） and aD colored flowing blood imaging （RT-3DCFI）. Re- suits 2-D ultrasonic Cardiographr could show position of electrode line of 26 cases（92. 8%） and position of the top of the line of 21 cases（95.8%）. 1 AAI pacemaker, and 1 DDD pacemaker, owing to pneumonectasia, the position of electrode line in right atrium could not be seen from many directions. In the other 26 cases（92.8%）, using single-cavi- ty or two-cavity pacemakers,satisfactory live 3D images were shown. Conclusions Live 3D ultrasonography shows a more straight,exact live image than 2D. It shows the position of the electrode line of pacemaker in heart, the relation with its surrounding structure and the changes of activities of tricuspidalis.
