The success rate and recurrence rate of radiofrequency ablation are closely related to the experience and proficiency of the surgeon. In the late 1980s, when radiofrequency ablation was first introduced, not only did it take 4-8 hours or even longer, but the success rate of the procedure was low and the recurrence rate was high. With the continuous improvement of this technology, the success rate of radiofrequency ablation has been greatly improved and the recurrence rate has been decreasing. For example, the success rate of atrial fibrillation tachycardia (paroxysmal supraventricular tachycardia, preexcitation syndrome) is 95% to 99%, and the recurrence rate is 2% to 5%; the success rate of atrial tachycardia and atrial flutter is 90% to 95%, and the recurrence rate is 5% to 10%; the success rate of idiopathic ventricular tachycardia is 90% to 95%; the recurrence rate is 5% to 10%. The success rate of the first surgery for paroxysmal atrial fibrillation is 80%-85%, and about 20% need to do a second time. The recurrence of radiofrequency ablation is mostly within a few months to 1 year after surgery. However, even if a recurrence occurs, do not worry too much. The majority of patients will be successful after a second RF ablation.
