title: Failure of Serial Electrocardiograms to Exclude a Large Anterior Myocardial Infarction and the Role of Transesophageal Echocardiogram in Acute Myocardial Infarction.
abstract: When patients present with acute onset of chest pain suggestive of myocardial ischemia, immediate clinical decisions regarding thrombolysis, percutaneous transluminal coronary angioplasty, or both are usually based on the history and abnormal electrocardiograms and confirmed by the presence of abnormally elevated cardiac enzymes. However, there are potential limitations of the electrocardiograms and initial cardiac enzymes in the diagnosis and confirmation of acute myocardial infarction. We describe the case of a patient who presented with an acute onset of chest pain and had a normal electrocardiogram and initial cardiac enzymes yet was found by transesophageal echocardiography to have a large myocardial infarction.
