我们在前一段工作中报导了冠心病患者的高频心电图QRS波出现很多高频切迹,与正常人比较有非常显著的统计学意义,高频心电图作为冠心病早期诊断的一种方法,具有特异性高,假阳性少,比常规心电图和双倍二级棉运动试验敏感等特点。本文报导家兔试验性急性心肌缺血时高频心电图的变化。实验用成年家兔24只,体重2公斤以上,雌雄不拘,乌拉坦全麻下进行。用SJ—41型多导生理记录仪记录Ⅰ、Ⅱ、Ⅲ、avR、avL、avF及胸前导联C1、C2、和C3。
We reported in the previous work of patients with coronary heart disease HF QRS wave appeared a lot of high-frequency notch, compared with normal people have very significant statistical significance, high-frequency ECG as a method of early diagnosis of coronary heart disease, with High specificity, less false positives, more sensitive than conventional electrocardiogram and double two-level cotton test. This article reports the changes in high-frequency electrocardiograms in experimental acute myocardial ischemia in rabbits. Twenty-four adult rabbits were used in the experiment, with a body weight of 2 kg or more, both male and female, under general anesthesia with urethane. Type I, II, III, avR, avL, avF and precordial leads C1, C2, and C3 were recorded with a SJ-41 multi-channel physiologic recorder.
