介绍一种观察心电图QRS波上高频切迹的方法。观察到90例心绞痛病人中,平静心电图正常者26人,可通过本法检出高频切迹。心肌梗塞病人的QRS波上高频切迹明显多于正常人及心绞痛病人。认为通过本法可发现较多隐性冠心病人,有个别冠心病人检出切迹较多,尔后发生心肌梗塞,是否可通过本法预测心肌梗塞,有待进一步观察探讨。讨论了本法存在的缺点。
A method of observing the high frequency notch on the QRS wave of ECG is introduced. Observed 90 cases of angina patients, the normal electrocardiogram of 26 people can be detected by this method high-frequency notch. QRS wave in patients with myocardial infarction significantly higher frequency notch than normal and angina patients. It is considered that more occult coronary heart disease patients can be found by this method, and some individual coronary heart disease patients have more cutouts and subsequent myocardial infarction. Whether myocardial infarction can be predicted by this method remains to be further investigated. Discussed the shortcomings of this law.
