EKG Abnormalities I. Early repolarization abnormality: A. A normal variant. Early repolarization is most often seen in healthy young adults. Look for ST elevation, tall QRS voltage, "fishhook" deformity at the J point, and prominent T waves. ST segment elevation is maximal in leads with tallest R waves.
