Discrepancy between early and late electrocardiographic indices of myocardial ischemic involvement in a patient with acute myocardial infarction.
A patient with acute myocardial infarction is described who showed marked ST-segment elevation in the ECG early in the course of his illness. Electrocardiograms at discharge, clinical course, myocardial scintigraphy and enzyme levels were suggestive of myocardial necrosis less extensive than expected from the magnitude and extent of intial ischemic injury by ECG. The factors which could have contributed to the modification of natural course of ECG evolution in this case are discussed.
