| Abstract: | We designed a set of animal experiments and made two models of acute muscle infarction by ligating the upper segment and lower part in left branch of coronary of rabbit heart. By using the chaos analysis methods, we performed some researches in the models of acute muscle infarction. We also presented the experimental plan, theory and arithmetic. The correlation dimension of synchronous 12?leads ECG signals of three rabbits under different pathological states were computed with normal state. After the analysis of all the data, we found the dynamic correlation dimension variety graph can qualitatively reflect the variety process of the heart in myocardial ischemia state and approved the value of correlation dimension in the research of heart electric activity. Therefore, we could use the correlation dimension to reflect the symptom of acute muscle infarction. |
