title: [Emergency epicardial dissection of the accessory pathway in a patient with atrioventricular nodal reentrant tachycardia].
abstract: Diagnostic and therapeutic problems in 14 year old patient with concealed WPW syndrome were presented. Paroxysms of atrio-ventricular reentrant tachycardia 180-220/min were frequently recurring, usually with normal QRS pattern. Tachycardias often had to be terminated by intravenous administration of antiarrhythmic drugs. Long term treatment with various antiarrhythmic agents did not prevent recurrence of tachycardias but they became sustained and were recurring more often. Their other side effects manifested with sinus node disfunction and depression of the heart muscle. The electrophysiologic study revealed right anterior septal accessory pathway. Epicardial dissection of the accessory pathway was urgently performed. The control electrophysiologic study revealed no evidence of conduction through the accessory pathway. The patient did not require antiarrhythmic treatment. During the 12 months follow up no tachycardia occurred.
