摘要
结扎家兔冠状动脉左室支的不同部位，用高频心电图三维谱分析法观察中高频成分、甚高频成分的变化，结果表明：缺血范围小于３５％，中高频成分、甚高频成分随缺血范围的增大而增加，缺血范围大于３５％时，中高频成分、甚高频成分减少。
The different parts of the left ventricular branches of rabbits coronaryartery were ligated,the changes of middle一high frequency and very high frequency contentswere observed with three dimensional spectrum analysis of high frequency electrocardiogram,The result demonstrated that when the ischemic size was less than 35%,the middle一highfrequency and very high frequency contents increased with the enlargement of the ischemicsize. But they decreased when the ischemic size was more than 35%.
