'''[[Early Repolarization]]''' is a term used originally 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>

In fact, though this new, rare syndrome may be found to be more prevalent now that it has been discovered, nomenclature and ECG measurement disagreements could result in more harm than good. This is particularly the case since many of the widely used automated ECG machines put out a statement of ''Early Repolarization'' based on ST elevation in an otherwise normal ECG.
