有关缺血性心律失常的机制研究历史已久,但至今尚未完全阐明。动物实验和临床研究表明发生于心肌缺血不同阶段的心律失常,其机制可能各不相同,治疗也有所区别。再灌注心律失常是心律失常中的新问题,其发病机制有别于缺血性心律失常。本文旨在讨论再灌注和不同缺血阶段心律失常的发生机制和防治问题。一、超急性期心律失常 1.表现发生在冠状动脉梗阻6小时内,常见的心律失常有:
The mechanism of ischemic arrhythmia has been studied for a long time, but it has not yet been completely elucidated. Animal experiments and clinical studies have shown that arrhythmias occur in different stages of myocardial ischemia, the mechanism may vary, the treatment is also different. Reperfusion arrhythmia is a new problem in arrhythmia, its pathogenesis is different from ischemic arrhythmia. This article aims to discuss the reperfusion and different stages of ischemia arrhythmia mechanism and prevention and treatment problems. First, the ultra-acute arrhythmia 1. Performance occurs within 6 hours of coronary artery obstruction, common arrhythmias are:
