摘要: 为了解大鼠心肌缺血性早期心律失常变化的规律及其与再灌性心律失常之关系,观察了大量在结扎和放松冠脉时的ECG,发现:①缺血30min内,62.3%出现室性心律失常的动物表现为即刻室性心律失常(IVA)及延迟室性心律失常(DVA)两个时相,②缺血时间与再灌注性室性心律失常的程度有关;③缺血性室性心律失常的类型与再灌注性室性心律失常的类型有关.

Abstract: In order to understands the regularity of early myocardial ischemic arrhythmia and the relationship between ischemic and repurfusion arrhythmias on rats,SD rats were studied. Our conclusion is that: ①There are two phases arrhythmias(IVA and DVA)on 62.3 % myocardial ischemic rats;② Repurfusion arrhythmia was influenced by ischemic time and ③there is some relationship between ischemic arrhythmia and repurfusion arrhythmia.

Key words: ventricular arrhythmia, ischemia and repurfusion injury, ECG, rats
