'''Early repolarization''' is a term used for ST segment elevation without underlying disease. It probably has nothing to do with actual early repolarization. It is commonly seen in young men. It is important to discern early repolarization from ST segment elevation from other causes such as [[ischemia]]. Characteristics of early repolarization are:<cite>Kambara</cite> | '''Early repolarization''' is a term used for ST segment elevation without underlying disease.
