Conclutions: Under ischemic condition, the decrease of Iks could prolong the mid-late repolarization phase of APD. It could cause EAD and then arouse TdP. Because the decrease of M cell was significantly greater than that of sub-endocardial myocytes and sub-epicardial myocytes, it could increase TDR. Cardiac arrhythmias could last due to reentrance that secondary the increase of TDR.

缺血时，心肌细胞的Iks电流减弱，使得细胞动作电位复极中后期延长，容易出现EAD并引发TdP；由于M细胞的Iks电流减弱程度明显大于心内、外膜细胞，造成心室跨壁复极离散度增加，有利于折返的发生，使得心律失常得以持续。

For the purposes of the study, NCCP was defined as noncardiac chest pain presenting as substernal chest pain in the absence of significant epicardial coronary artery stenoses.

作者们解释，因此，这项研究的目的，以未发生显著心脏表面冠状动脉狭窄的情况下，发生胸骨下胸痛的非心因性胸痛来定义。

Furthermore, we analyzed the possible mechanism. Methods: We established the arterially perfused rabbit left ventricular wedge preparations to record transmembrane ECG and action potentials of the epicardial cells and endocardial cells simultaneously. We divided two groups by setting the location of premature beats.

A rate-limiting step to long-term survival in heart transplant patients is coronary arteriopathy, which is marked intimal proliferation with lumenal narrowing of the small epicardial and intramyocardial coronary artery branches, leading to ischemic changes.

限制心脏移植的患者长期存活的关键步骤是冠状动脉病，心外膜和心内膜的冠状动脉的小分支动脉内膜增殖，管腔狭窄而导致心肌缺血性的改变。

A rate-limiting step to long-term survival in heart transplant patients is coronary arteriopathy, which is marked intimal proliferation with lumenal narrowing of the small epicardial and intramyocardial coronary artery branches, leading to ischemic changes.

冠状动脉影响到心脏移植病人能否长期存活，它的特征有内膜增生伴有心外膜以及心肌内的冠状动脉分支管腔狭窄，从而导致缺血性改变。

Epicardial mapping is a method of observing, detecting and analyzing cardiac electropotential signals with precision.

心外膜Mapping标测是一种精确测量和观察分析心脏电活动的方法，辅以直观的实时显示图能为外科及内科医生提供一条准确迅速的判断指标。

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。

The mean fluoroscopy times for endocardial and epicardial mapping were 27±23 seconds (range, 0 to 105 seconds) and 18±18 seconds (range, 0 to 49 seconds), respectiely.
