title: The early repolarization variant--an electrocardiographic enigma with both QRS and J-STT anomalies.
abstract: A detailed description of the electrocardiogram of the early repolarization variant, including its most common morphological variations is presented. Included is a recently identified anomaly of the QRS complex, which has not previously been reported. Ventricular activation data is presented to explain the unique QRS changes. A comparison with Wolff-Parkinson-White (preexcitation) reveals certain similarities related to a premature completion of depolarization in early repolarization variant.
