高频心电研究开展已有４０余年的历史，但至今尚无法应用于临床，未获突破性进展问题的实质，在于高频心电形成的因素很多，机理未明，表面上看起来特异性不明显，单靠一般的统计法研究，难以探明高频心电的生成机理，因此高频心电一时还无法作为临床早期诊断的有效方法。本文通过用狗的心脏进行模型实验，研究狗心脏产生人为创伤模拟病变与高频心电表现的确切关系，以及高频心电的可利用性。同时指出，目前国内外部分学者采用统计切迹（ｎｏｔｈ）和转折（Ｓｌｕｒ）的总数来讨论与某些心脏疾病之间关系的方法是不够确切的，因为通过动物试验表明，切迹和转折的数目非心脏病变的唯一标志，告诫对此必须进行十分必要的特征提取。
High-frequency ECG research has been carried out for more than 40 years of history, but so far still can not be applied to clinical, unobstructed progress in the essence of the problem is that there are many factors in the formation of high-frequency ECG, the mechanism is unknown, seemingly specific Obviously, relying solely on statistical methods to study, it is difficult to ascertain the generation mechanism of high-frequency ECG, so high-frequency ECG for a while still can not be used as an effective clinical early diagnosis. In this paper, the dog’s heart model experiments to study dogs with heart-induced traumatic simulated lesions and the exact relationship between the performance of high-frequency ECG, and the availability of high-frequency ECG. At the same time, it is pointed out that at present, some domestic and foreign scholars use the total number of noth and Slur to discuss the relationship with some heart diseases is not exact enough, because animal experiments show that notch and transition The number of non-cardiac lesions is the only hallmark that warrants having to extract the very necessary features.
