ST Elevation and Inverted T Wave as Another Normal Variant Mimicking Acute Myocardial Infarction: The Prevalence, Age, Gender, and Racial Distribution

摘要

Background: Early repolarization (ERP) as a normal variant is a well-recognized ECG entity. There is another normal variant of ST elevation (STTNV) in the midprecordial leads, which is distinctively different from ERP in that the T waves are inverted in these leads while they are upright and tall in ERP. These findings can be easily mistaken for acute myocardial infarction or pericarditis. The purpose of this study is to publicize this entity and to determine its prevalence, age, gender, and racial distributions.
