摘　　要：目的探讨超声心动图指导下优化希氏束起搏患者房室间期的效果。方法选取自2017年10月至2018年6月沈阳军区总医院接受希氏束起搏器置入的20例高度房室传导阻滞患者为研究对象。超声心动图指导下记录并比较术前及术后不同房室间期的参数变化。结果术后3 d调节80～160 ms房室间期,左心室舒张末期容积,左室收缩末期容积、左室射血分数与术前比较均有所减小,差异均无统计学意义(P> 0. 05)。心室间机械延迟、左心室充盈时间占心动周期与术前比较,差异有统计学意义(P <0. 05),且房室间期120 ms时,左心室充盈时间最长。结论希氏束起搏可以改善高度房室传导阻滞患者的心脏运动同步性,超声指导优化房室间期简便可行,可获得良好的血流动力学效果。Objective To investigate the optimal physiological for patients with his bundle pacing(HBP)by using echocardiographic parameters.Methods A retrospective study was performed on 20 cases of patients with his bundle pacing who were admitted from October 2017 to June 2018.Echocardiography was used to record and compare the change of parameters in different interatrial and interventricular phases before and after operation.Results Three days after the operation,80 to 160 ms of AV interphase was adjusted,the LVEDV,LVESV and LVEF were reduced,and the difference was not statistically significant(P>0.05).Ventricular mechanical delay and left ventricular filling time in cardiac cycle were statistically significant compared with preoperative results(P<0.05),and left ventricular filling time was the longest when the interatrial period was 120 ms.Conclusion His bundle pacing can improve synchronous movement of patients with high degree AVB,program-controlled HBP under the guidance of ultrasound can further improve hemodynamic effects.
