目标：多时相室间隔运动和间隔-侧壁心尖左心室(LV)运动为左束支传导阻滞的心电图特征。
Objective: Multiphasic septal motion and septal to lateral apical left ventricular (LV) motion are echocardiographic characteristics of left bundle branch block.
应用经食管超声心动图获得二维图像，全方向M型超声显示并测量房间隔运动时的厚度、波幅时间及速度。
Two dimensional image was obtained by transesophageal echocardiography. The thickness, wave time and velocity were showed during atrial septal motion by omni directional M mode echocardiography (OME).
结论：多时相室间隔运动或典型的心尖“移动”对进行CRT后长期LV逆向重塑的预测效果与用组织多普勒定量检测LV不同步性的预测效果相当。
Conclusion: Multiphasic septal motion or typical apical 'shuffle' predicts long-term LV reverse remodeling after CRT comparable to quantitative determination of LV dyssynchrony with tissue Doppler.
