Abstract
Others have described mild or atypical myocardial infarction as a clinical condition in which the pain is of short duration and the evidence of tissue damage is slight. It occurs in otherwise healthy individuals and is characterized by complete recovery and the absence of complications. In this study the electrocardiograms of 359 patients with myocardial infarction were divided according to the QRS complexes; one group showing normal QRS complexes and the other showing typical Q waves. The clinical features of the patients in these two groups were compared.
