title: [2 episodes of ventricular fibrillation in a patient with mild paroxysms of Wolff-Parkinson-White syndrome].
abstract: In a patient with an overt Wolff-Parkinson-White syndrome and short paroxysms of atrio-ventricular tachycardia, episodes of atrial fibrillation occurred twice at age of 21 and 24. Atrial fibrillation degenerated into ventricular fibrillation. Intravenous injection of verapamil in this patient (with a short refractory period of the accessory pathway) could have facilitated ventricular fibrillation. The patient was resuscitated successfully. Electrophysiologic study revealed double accessory pathways--in the left free wall (effective refractory period in both directions--below 200 ms) and right posterior ++para-septal localization. 20th Nov 1990 A. Biederman M.D. performed surgical dissection of both accessory pathways. In control electrophysiologic studies there was no evidence of abnormal atrio-ventricular conduction. During one year follow up the patient reported no paroxysms of tachycardia.
