Abstract:
QT dispersion has been cited as a measure of nonuniform myocardial repolarization and a predictor of sudden cardiac death. We describe 38 patients who underwent atrioventricular nodal ablation, 3 of whom had an increase in measured QT dispersion and experienced potentially fatal, pulseless, polymorphic ventricular tachycardia after the procedure.
