急性缺血是导致室性心律失常、心脏性猝死的主要原因之一。本研究以经冠状动脉灌注的兔左心室楔形心肌组织块为对象,着重探讨了急性无灌注缺血过程中兔左心室内外膜心肌动作电位、跨壁复极离散度(transmural dispersion of repolarization,TDR)演变规律及室性心律失常发生机制。资料和方法
Acute ischemia is one of the main causes of ventricular arrhythmias and sudden cardiac death. In this study, rabbit left ventricular wedge-shaped myocardial tissue mass perfused with coronary artery was taken as the object to investigate the effects of transmural dispersion of repolarization (TDR) ) Evolution and ventricular arrhythmia mechanism.
