'''Early repolarization''' is a normal variant of the ST segment, seen in 2-5% of patients, especially young men. Early repolarization is characterized by elevation of the J point and the beginning of the ST segment as well as elevation of the ST segment itself<cite>Wellens</cite>. The ST segment may be concave up (cup-like) or concave (dome-like). These findings are most often present in the middle chest leads V2-V5. | |||
Recently a different form of early repolarization has been associated with idiopathic ventricular fibrillation. This form is most often seen in lead II and consists of a 'hump' in the tail of the QRS complex, without ST elevation. | |||
