Cardiac radiofrequency ablation is a treatment for the eradication of rapid arrhythmias, and its cost varies according to the type of arrhythmia of the patient, as follows: 1, paroxysmal supraventricular tachycardia, pre-excitation syndrome, ventricular premature, idiopathic ventricular tachycardia, the operation cost is about 20,000 yuan; 2, atrial fibrillation radiofrequency ablation cost is about 60,000 yuan; 3, radiofrequency ablation in two-dimensional situation is less expensive; radiofrequency ablation under CARTO three-dimensional electroanatomical specimen measurement is relatively high.
