摘　　要：目的评估经胸超声心动图在左束支区域起搏电极定位中的作用。方法选取2018年11月至2019年11月期间成都市第三人民医院心血管内科因房室传导阻滞入院并拟行左束支区域起搏治疗的患者。术后利用经胸超声心动图对左束支区域起搏电极位置、植入深度、植入角度、电极植入点距离三尖瓣环距离、电极头端距离左室心内膜间隔面的距离等进行评估。结果27例患者均完成起搏器植入,25例成功完成左束支区域起搏,1例为室间隔内起搏,术后超声监测1例发生电极穿孔。22例可通过经胸超声心动图对左束支区域起搏电极进行定位,其余5例因声窗受限不能准确显示电极位置、走行及其与周围结构的关系。室间隔内平均电极植入深度为(12.2±2.2)mm,电极头端距离左室内膜面平均1.9(1.0,2.5)mm。结论经胸超声心动图对左束支区域起搏术后电极有较好的评估价值。Objective To investigate the role of transthoracic echocardiography in the location of left bundle branch area pacing(LBBAP)electrodes.Method A total of 27patients who prepared for LBBAP from November 2018to November 2019in department of cardiology of the third People′s Hospital of Chengdu were involved.Transthoracic echocardiography was used to evaluate the position,lead depth,implantation angle,the distance from the left ventricular endocardial surface and tricuspid annulus to electrode implantation site after operation.Result All 27patients completed pacemaker implantation.LBBAP was successfully completed in 25patients,ventricular septal pacing was performed in 1patient,and electrode perforation was happened in 1patient.Twenty-two patients could locate electrode by transthoracic echocardiography,and the other 5patients could not precisely locate electrode due to the limitation of acoustic window.The lead depth was approximately(12.2±2.2)mm,distance between electrode tip and left ventricular endocardial surface was approximately 1.9(1.0,2.5)mm.Conclusion Transthoracic echocardiography can be used to locate pacing electrodes of LBBAP.
