Clinical analysis of radiofrequency catheter ablation on paroxysmal supraventricular tachycardia

Objective This study was to analyze the outcomes of patients with paroxysmal supravetricu1ar tachycardia after therapeutic radiofrequency catheter ablation for further clinical operating works.Methods Clinical data of 382 patients with different supravetricu1ar tachycardia received radiofrequency ablationtherapy were retrospectively analyzed.Results There were 174 patients with atrioventricular reentrant tachycardia.Among them,there were 113 cases with left accessory pathways,61 cases with right accessory pathways.There were 208 patients with atrioventricular nodal reentrant tachycardia.The overallsuccess rate was 97.4%,in which radiofrequency catheter ablation of paroxysmal supraventricular tachycardia mediated by dual atrioventricular nodal and left accessory pathway had a higher success rate(98.4%).The overall recurrence rate was 2.6% and the incidence of complications was 1.8% after radiofrequency catheter ablation.Conclusion Radiofrequency catheter ablation is an effective and safe therapeutic method with high successful rate,low incidence of complications for patients with paroxysmal supravetricu1ar tachycardia.The patients with right accessory pathway had a higher recurrence rate.
