Abstract
Outflow tract ventricular tachycardia (OT-VT) was successfully ablated from the right coronary cusp of the aortic valve, The 12-lead ECG was totally d ifferent from the typical right ventricular OT-VT because the R/S ratio in precordial lead V-1 was equal to 1 and tall R waves in precordial leads V2- 6 were seen. Radiofrequency energy application from the right coronary cusp of the aortic valve successfully ablated this VT without complications. Ra diofrequency catheter ablation from the right coronary cusp of the aortic v alve can be done safely and effectively.
