您要查找的是不是：
- DTI can be used to localize abnormal ventricular activation origin and assess contraction sequence accurately and non-invasively. DTI技术无创、安全、可重复的特点，可以使其作为电生理检查的补充，广泛应用于临床。
- Equilibrium radionuclide angiography(ERNA) phase image analysis was performed after operation. Ventricular activation sequence and biventricular contraction synchrony during RVS and RVA pacing were compared with those of the intrinsic rhythm. 术后进行核素心室显像位相分析 ,对比自身心律与RVA和RVS起搏时心室激动顺序和双心室同步性的差异。
- Tissue synchronization imaging and tissue tracking are very sensitive to time events, and can observe the ventricular activation sequence, delay contraction and asynchronization in LBBB. 结论LBBB者心肌运动不同步明显，组织同步成像和组织追踪技术能敏感检测到心室激动顺序，出现收缩延迟及收缩不同步。
- vector of terminal ventricular activation 终未心室激动向量
- ventricular activation time, VAT 心室激动时间
