Abstract: Objective To study and compare the clinical value of ECG in the diagnosis of irritable cardiomyopathy and acute anterior wall myocardial infarction, and further improve the accuracy of early diagnosis. Methods The electrocardiograms of patients with two diseases were compared and analyzed. Results The results indicated that there were more obvious differences in electrocardiogram(ECG)characteristics between the two diseases on the distribution of ST segment elevation lead, lead wall under stress cardiomyopathy distribution ratio was significantly higher than that of anterior wall acute myocardial infarction, and significantly less than in V1 lead acute anterior wall myocardial infarction; Acute anterior wall myocardial infarction -aVR leads ST segment elevation was significantly less than that of stress cardiomyopathy. The incidence of pathological Q wave in irritable cardiomyopathy was significantly lower than that of acute anterior wall myocardial infarction, and it had the characteristics of transience and reversibility, which was different from acute anterior wall myocardial infarction. Most of the acute anterior wall myocardial infarction had a mirror change, and there was little in stress cardiomyopathy. Conclusion Stress cardiomyopathy electrocardiogram(ECG)and acute anterior wall myocardial infarction different performance have a certain value in the early differential diagnosis.

Key words: stress cardiomyopathy, acute anterior wall myocardial infarction, electrocardiogram(ECG)
