Abstract
We present a case of a 19-year old man with minor Ebstein’s anomaly, intermittent long QT interval and WPW syndrome in whom atrial fibrillation, degenerating into ventricular fibrillation was the first symptom. QRS complex morphologies during atrial fibrillation revealed the presence of three accessory pathways (septal, right inferior paraseptal and antero-inferior). Immediately after resuscitation the patient was treated with amiodarone, which resulted in a significant prolongation of QT interval to 700 ms. After RF ablation of accessory pathways patient remains asymptomatic during 6-month follow up, however QTc interval is about 500 ms.
