The procedure required for atrial flutter patientology is electrophysiological examination plus radiofrequency ablation. The total cost of the procedure is about 70-80,000 yuan, which is the cost before reimbursement, and about 30-40,000 yuan after reimbursement of out-of-pocket expenses, depending on the percentage of reimbursement in the province and city. RF ablation of atrial flutter has a certain percentage of recurrence, the overall success rate is about 80%, some patients will recur after the procedure and may undergo 2 times of RF ablation. In our center, for example, the second procedure will reduce the cost of the procedure by half, and the patient will need to take antiarrhythmic drugs and antithrombotic drugs for a certain period of time after the procedure.
