Generally, cardiac radiofrequency ablation is performed for arrhythmia. Such as preexcitation syndrome, frequent ventricular premature beats, atrial flutter, atrial fibrillation, etc. Generally, tachyarrhythmia occurs frequently and drug control is not ideal. In this case, radiofrequency ablation will be considered. For example, the preexcitation syndrome can be eliminated by radiofrequency ablation, and the congenital bypass can be removed. Atrial fibrillation can still recur and the control is not ideal through antiarrhythmic drugs. In this case, radiofrequency ablation can also be used to electrically isolate the pulmonary vein and terminate the onset of atrial fibrillation, especially paroxysmal atrial fibrillation. The cure rate is very high. Of course, if the patient has a long history of left atrial enlargement, there is also a certain recurrence rate. Therefore, whether there are indications and contraindications for surgery depends on the specific condition of the patient.
