[A retrospective study of 4865 cases of paroxysmal supraventricular tachycardia treated with catheter ablation].

In recent 10 years, using radiofrequency catheter ablation, our medical center has treated 4865 cases of paroxysmal supraventricular tachycardia (PSVT). To improve clinical practice, a retrospective analysis of this group was made. In this group, 2092 cases were atrioventricular reentry tachycardia (AVRT), including 1415 left accesory pathway and 677 right accesory pathway, and 2773 cases were atrioventricular nodal reentry tachycardia (AVNRT). The total success rate of radiofrequency treatment is 99.71%; the recurrence rate after half a year 1.73%; the total complication rate 1.25%. In conclusion, radiofrequency ablation is a safe and effective treatment for tachycardia with high rate of success and low rate of complication.
