title: Silent acute myocardial infarction masked by transient WPW syndrome.
abstract: A case with transient WPW syndrome during silent acute myocardial infarction is presented. Although the clinical picture and laboratory data were non contributory and the surface electrocardiogram showed delta and not Q waves, myocardial perfusion scintigraphy showed typical area of acute necrosis. Abnormal accessory connections probably occur or latent such pathways become functional during acute myocardial ischemia.
