    Abstract:
    Eleven patients (9 male, 2 female) with ventricular tachycardia (VT) and structurally normal heart underwent radiofrequency (RF) ablation of VT focus. The detailed electrophysiological mapping localized the VT focus in the left ventricular (LV) apicoseptal region in 5, LV posteroseptal region in 2, right ventricular (RV) outflow tract in 2 and RV midseptal and inflow regions in one patient each. The technique of endocardial activation mapping during VT, pacemapping and the presence of His-Purkinje potential (for LV focus) were used to identify the precise site of delivery of RF energy. The procedure was successful in 9 patients. There was no complication. The mean fluoroscopic time was 45 +/- 21 (range 20-120) minutes. RF ablation is effective and may be considered as therapy of choice for patients with ventricular tachycardia and normal heart.
