High-frequency electrocardiogram ECG has been developed for more than 40 years and it is still not applied to clinic because there are some facts of causing high-frequency ECG HFECG and its mechanism are not understood well, and the idiosyncrasy of patients appears not too clear formerly. We are interested in the study of high-frequency information HFI in QRS complex and use animal models and some extraction methods to make sure its producing mechanism. The purpose of this article is to describe some good results which could explains some phenomena, that is high-frequency notching located on QRS complex associated with myocardial injuries in which the small injury area exactly related with injecting formalin or ligaturing coronary artery. We also pointed that notching processing are necessary, and supplementary parameters should be adopted, that the HFI has very useful value of idiosyncratic, local, early and dynamic characteristics for early diagnosis.
