The effectiveness of radiofrequency ablation procedures depends mainly on the type of arrhythmia. For patients with paroxysmal, supraventricular tachycardia, the cure rate can reach 95%-98% after radiofrequency ablation treatment. Therefore, radiofrequency ablation is usually recommended for such patients. In other cases, the cure rate of ventricular premature beats and atrial premature beats is more variable. The location of the origin of the premature beats or the number of points of origin may have an impact on the outcome. Depending on the site, the success rate may vary. The protocols for radiofrequency ablation of atrial fibrillation are basically consistent and have a very fixed process. Nowadays, the success rate of radiofrequency ablation is generally 70%-80% for the first time when it can treat general paroxysmal atrial fibrillation, other heart diseases are excluded, and the left atrium is not very large. For the second time, the success rate can be further improved, and some reports can reach 90%. For persistent atrial fibrillation, it is not impossible to perform radiofrequency ablation. However, after a series of evaluations by the physician, the success rate of the procedure will vary by understanding the structure of the heart, the size of the left atrium, and the duration of the patient’s atrial fibrillation, but the success rate may be slightly lower than that of paroxysmal atrial fibrillation.
