In the electrocardiographic diagnosis of recent myocardial infarction, so much emphasis has been placed on the S-T-T configuration, because of the diagnostic value of its evolution, that the importance of the QRS pattern has been insufficiently stressed. Recent experience has shown that several conditions such as acute diffuse pericarditis,1 acute cor pulmonale,2 acute nephritis,3 toxemias of pregnancy,4 hyperthyroid state in flux,5 etc., may sometimes closely imitate the S-T-T pattern of myocardial infarction and less closely its evolution, without showing the specific QRS patterns expected in myocardial infarction. It therefore seemed desirable to investigate the QRS patterns encountered in recent myocardial
