Abstract

A 23-year-old woman with pre-excitation who was resuscitated from ventricular fibrillation underwent electrophysiologic testing. Successful catheter ablation of a left posteroseptal accessory pathway was achieved. Though the JT and JTc intervals as well as QT and QTc intervals were prolonged before and one day after the ablation, they normalized within about 5 hours after the ablation. This case demonstrated that in a patient with pre-excitation and long QT syndrome (LQTs), the JTc interval was useful for diagnosing LQTs and a longer follow-up of the JTc interval after the ablation was necessary in order not to miss the diagnosis of LQTs.
