The aim of this study was to compare the results of radiofrequency catheter ablation (RFA) in patients (pts) with idiopathic and secondary ventricu lar tachycardia (VT). Sixty-six pts with monomorphic VT (1 I female, 55 m ale; m ean age 35.5± I 5.6 years, range I 0-75 years) were included. Forty-one pts presented with idiopathic (21 right ventricular outflow tract, 20 left ventricular VT) and 25 pts presented w ith secondary VT ( I 2 ischaemic, 5 arrythmogenic right ventricular dysplas ia, 3 dilated cardiomyopathy, I hypertrophic cardiomyopathy, 2 bundle branch reentrant tachycardia, I mitral valve prolapse, 1 post-operative). The mean duration of symptoms w as 73.1 ±77 months in idiopathic VT group and 37±38 months in secondary VT group (p<0,03). The pts in idiopathic VT group had prev iously received a mean of 2.79± 1.5 antiarrhythmic drugs, and a mean of 3.63±1.6 antiarrhythmic drugs were adınİnistered to the pts in secondary VT group. The mean number of RF pulses delivered to the 40 pts in idiopathic VT group (5.7±5) was significantly lower (p<0.05) than pls in secondary VT group (12.2+10). Primary success rate was 80% (20 of 25 pts) in secondary VT group and 92.6% in idiopathic VT group (38 of 4 ı pts). The m ean total d uration of the procedure w as ı ı 4±43 minules in idiopathic VT group and 144±75 minutes in secondary VT group. No serious complications occurred in both groups. Pts were followed for a m ean of 28.3± I 9 months in idiopathic VT group and 50.3±20.7 months in secondary VT group (pKeywords: Ablation, idiopathic, secondary, ventricular tachycardia
