In contrast, Prinzmetal et al.⁵ claim that an acute myocardial infarction may fail to alter the electrocardiogram. The statement is based on their dog experiments, ^6,7 which showed that diffuse lesions of the deeper layers of the myocardium, especially the subendocardium, did not produce abnormal tracings. They also observed two persons with pure subendocardial lesions which were diagnosed only after death. One patient died of carcinoma of the stomach, and the other, of pneumonia; both had essentially normal electrocardiograms.

This report is a study of the electrocardiograms of 304 cases of myocardial infarction as proven at autopsy. The autopsies were . . . [Full Text PDF of this Article]
