摘要
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。
tudy of high-frequency electrocardiogram has been developed for more than 40 years of history. But it is still not applied to clinic. The reason is that there are a great number of difficulties left,such as so many fsctors causing high-frequency ECG and its mechanism are unknown,and the idiosyncrasy appears not clear outwardly. In this case,it is hard to verify the existence methods areuSed to solve the problems and purely relied upon. Therefore,the high-frequency ECG is not used asan effective method of clinical early diagnosis for the moment. We have worked on the behavior anditS utilization of high-frequency ECG through studying dog's heart as a modelling experiment and indicated the fact that the method of studying the relationship betWeen Statistical toeal notches and slursand some heart discuses currently used by scientists at home and abroad,is not precise. We pointedout that the total numberts of notches and slurs are not the only symptoms with some heart disusesand pattern recognizing and processing,are needed to sdopt supplementary parameters.The proest is subsidiized by National Natural Science Foundation of China.
