摘要
结扎家免冠状动脉左室支的不同部位，观察QRS起始部、中部、终末部高频成分的变化，结果显示：缺血面积小于35％时，整个QRS波高频成分随缺血范围的增大而增加；缺血面积大于35％时，QRS波起始部、中部的高频成分减少。
The different parts of the left ventricular branches of rabbits' coronary artery were ligated, the high frequency components changes in beginning,middle and terminal of the QRS complex were observed. The result demonstrated that when the ischemia size was less than 35%, the high frequency components of entire QRS complex increased with the enlargement of the ischemia size. the high frequency components in the beginning and middle,of the QRS complex decreased when the ischemia slze was more than 35%.
