Successive myocardial infarctions in a patient with Mahaim fiber syndrome

A patient with Mahaim fiber syndrome suffered two acute myocardial infarctions during the last two years. Anomalous atrioventricular excitation was intermittent. Diagnosis of both anteroseptal and anterolateral electrocardiographic myocardial infarction could be made despite ventricular pre-excitation. These findings have not been previously published, to our knowledge.
