Wolff-Parkinson-White pattern is a relatively common electrocardiographic phenomenon caused by accessory atrioventricular (AV) conduction, which can make the diagnosis of acute myocardial infarction challenging. There is little existing literature regarding the interpretation of electrocardiograms in patients with accessory AV conduction pathways who present with acute myocardial infarction. We describe a case of electrocardiographic evolution of acute ST-segment elevation myocardial infarction in a patient with Wolff-Parkinson-White pattern, review pseudo-infarction patterns, and discuss proposed mechanisms for these repolarization abnormalities.
