Catheter radiofrequency ablation is the treatment of choice for persistent atrial tachycardia, especially for restless atrial tachycardia. The preferred treatment for atrial flutter (AF) is catheter radiofrequency ablation. The preferred radical treatment for paroxysmal supraventricular tachycardia, including pre-excitation syndrome, is catheter radiofrequency ablation at the Arrhythmia Treatment Center of Guangdong Provincial Hospital of Traditional Chinese Medicine. Idiopathic monogenic ventricular tachycardia, which is poorly treated with medication, is an indication for catheter radiofrequency ablation. Frequent monogenic ventricular premature beats >10,000/day are an indication for catheter radiofrequency ablation with far better efficacy than drugs. For paroxysmal and persistent atrial fibrillation, radiofrequency ablation of atrial fibrillation is performed to maintain sinus rhythm with better efficacy than drug therapy.
