Abstract
Pathologic Q waves on the surface electrocardiogram often reflect transmural myocardial infarction. Intraventricular conduction defects may sometimes be responsible for pathologic Q waves, erroneously suggesting infarction. In addition, evidence of myocardial infarction may be concealed by the deveopment of intraventricular conduction defects. This report describes a patient with acute diaphragmatic infarction in whom development of transient left anterior hemiblock (with possible septal fascicular block) concealed a diaphragmatic infarction and simulated anteroseptal infarction.
