title: Isolated T wave alternans progressing to QRS-T alternation after ventricular defibrillation.
abstract: A 54-year-old woman underwent replacement of a thrombosed Björk-Shiley aortic valve prosthesis. Post operative electrical defibrillation resulted in isolated T wave alternation which progressed to total QRS-T electrical alternans. This report represents the first description of such a phenomenon.
