Although the success rate of radiofrequency ablation in patients with supraventricular tachycardia is close to 100%, it is recommended that patients with supraventricular tachycardia undergo radiofrequency ablation at a large hospital with a high volume and a large number of patients, considering that any procedure involves a certain degree of risk. The success rate is relatively higher, and recurrence rates and surgical complications are much less common. Radiofrequency ablation of supraventricular tachycardia is not always as straightforward as it may seem. Some patients with supraventricular tachycardia may have difficulty because the bypass and bipath are too close to the AV node-Hirschsprung bundle, which may cause AV block (which would require a pacemaker) due to the fear of damaging the normal heartbeat pathway during the procedure. In addition, individual bypasses may be too deeply located to be completely eliminated. Therefore, only hospitals and doctors with considerable experience in these difficult cases of supraventricular tachycardia can identify the crux of the problem and find the key “winning” point, thus increasing the success rate of the procedure.
