The results indicated that mortality in patients occurring with QTc prolongation 、 left ventricular hypertrophy 、 bundle branch block 、 junctional rhythm or sinus tachycardia was high.

结果发现QTc延长、左室肥厚、束支传导阻滞、交界性心律或窦性心动过速时，死亡率增高。

Objective To assess abnormality of left ventricular torsion ( LVtor) with cardiac pacing and right bundle branch block ( RBBB) patients by two-dimensional ultrasound speckle tracking imaging ( STI), and demonstrate the rule of LV myocardium dynam during abnormal ventricular mechanical activation.

目的应用斑点跟踪显像（speckle tracking imaging，STI）技术评价心脏起搏和右束支传导阻滞（RBBB）的左心室旋转角度异常，初步揭示心室激动顺序异常时左心室心肌力学变化规律。
