At the BCL of 500ms, 1000ms and 2000ms,the VWtimes increased markedly with the BCL prolonging, and the degree of increasing was even obviously when heart rate was slow (BCL=2000ms or 1000ms). The enlargement of VWs was a most important reason to increase the incidence of ventricular arrhythmias; 2）At the BCL of 500ms, 1000ms or 2000ms,the VWtimes of the premature stimulates S2 was at endomembrane were wider than at the outermembrane. We supposed that premature stimulates come from endomembrane was easier inducing VF compared with outermembrane;3The VWtime of unidirectional block was wider than reentry's, we can see that reporlarization dispersion changed dynamicly. 4The QRS polar of the premature stimulates was opposite the primary beats ,which suggesting that excitation of inducing premature beats was coming from epicardial. That is to say electrotonic potential take part in the creation of reentry;5With the ratio of the Tp-e/QT increasing the occurrence of VF was upgrading. So the ratio was an effective method to estimate the event of SCD.6 The VWtimes of S3 were broaden than S2's. But we can not study penetratingly, which is the contents of our future studies.

在BCL为500ms、 1000ms和2000ms刺激条件下，随着刺激周长的增加单向传导阻滞时间易损窗呈增大趋势；并且在心率较慢时(BCL为2000ms和1000ms)增大最明显，是LQTS患者室性心律失常发生率增加的原因之一；2）在BCL为500ms、 1000ms和2000ms刺激条件下，S2位于内膜侧时时间易损窗大于在外膜侧时的，推测来自于内膜侧的期前刺激易于诱发室性心律失常；3）折返激动时间易损窗小于在单向传导阻滞时间易损窗，折返易发生于S2刚进入单向传导阻滞区间时，这说明复极梯度的不均一是动态变化的；4心电图上倒置QRS波与正常S1刺激所引起QRS波极性相反，提示不同位置S2刺激引发的室性早搏的兴奋均来自于外膜侧，说明了电紧张电位扩布参与了折返的产生；5）Tp－e/QT可以反应跨膜复极离散度，随着Tp－e/QT比值的增加PVT的发生增多，其可以用来预测室性心律失常的发生。6）随着期前刺激数目的增加时间易损窗增大。
