摘要:
结扎家兔冠状动脉左室支的不同部位, 用高频心电图时域频域法观察中高频成分、甚高频成分的变化。结果表明: 缺血面积小于35% 时, 中高频成分、甚高频成分随缺血范围的增大而增加; 若缺血面积大于35% 时, 中高频成分、甚高频成分减少。
Abstract:
After ligation of different parts of the left ventricular branches of rabbit coronary artery, the changes of middle-high frequency components and very high frequency components were observed with the method of time-frequency mapping of high frequency electrocardiogram. The results demonstrated that when the ischemic area was less than 35% ,the middle-high frequency components and very high frequency components were increased with the enlargement of the ischemic area, but the components were decreased when the ischemic area was larger than 35%.
