INTERVENTIONAL TREATMENT OF VENTRICULAR ARRHYTHMIA USING NON-INVASIVE ELECTROPHYSIOLOGICAL MAPPING IN A PATIENT WITH IVB GRADE VENTRICULAR EXTRASYSTOLES AFTER UNSUCCESSFUL RADIOFREQUENCY ABLATION
A case report of a 59 year old female patient with frequent symptomatic ventricular premature beats is given, in whom the computing electrophysiological study permitted one to determine the ectopic focus site and subsequently to eliminate by means of radiofrequency catheter ablation.
