摘　　要：1病例资料患者,男,21岁,发现心动过缓4年,病程中反复出现活动后心悸,多次心电图提示三度房室传导阻滞、交界性异搏。根据2016ESC指南建议,该患者三度房室传导阻滞诊断明确,且无可逆病因,起搏器植入指征明确。术前经胸超声心动图示:左房内径38 mm,左室舒张末期内径53 mm,室间隔厚度10 mm,左室射血分数(LVEF)62%,三尖瓣少量反流。予以DDD起搏器植入。起搏器植入过程中主要依靠术者经验、X线及腔内心电图粗略定位。A case about pacemaker electrodes in left bundle branch area observed by echocardiography is reported.The case showed a novel strategy to locate pacemaker electrodes in patients with left bundle branch area pacemaker.
