• <B>Aims:</B> We investigated whether the new contact mapping system, EnSite velocity system, is safe and effective for ablation of non-sustained ventricular tachycardia (VT) originating from the right ventricular outflow tract (RVOT). <B>Methods:</B> A 42 year-old women who was old handball player presented with palpitation and dyspnea. Holter and treadmill test showed non-sustained VT with left bundle branch block pattern. <B>Results:</B> In electrophysiology study, non-sustained VT was easily induced by isoproterenol infusion at more than 140 beat per min of heart rate. Voltage and activation mapping were performed with EnSite velocity system. After the ablation at anterior septum of RVOT, non-sustained VT was not induced. <B>Conclusion:</B> The new contact mapping system, EnSite velocity system, is effective and helpful for mapping and ablation of RVOT VT.
