Abstract:
Objective:To investigate the efficacy and safety of catheter radiofrequency ablation for ventricular tachycardia.Methods:Thirty-three patients with ventricular tachycardia were performed electrophysiologic study and radiofrequency ablation.Thirty cases with idiopathic ventricular tachycardia underwent pacemapping and/or activation mapping,and 3cases with arrhyththmogenic right ventricular cardiomyopathy underwent Carto system mapping.During the average follow-up of 28?17 months,acute successful rate and long-term successful rate of radiofrequency ablation were recorded ,and safety was observed.Rsults:①For radiofrequency ablation,the acute successful rate was 90.9%(30/33),and 3 cases without successful ablation were with idiopathic ventricular tachycardia;long-time successful rate was 87.9%(29/33),and 1 case with arrhyththmogenic right ventricular cardiomyopathy reoccurred.②Ventricular responses were induced by radiofrequency ablation in all successful cases.③No complication occurred.Conclusions:Successful rate and safety of radiofrequency ablation for ventricular tachycardia were high;and the ventricular responses during ablation could be the predictors for successful ablation.
