Radiofrequency ablation surgery is performed through the following aspects: 1. do intracardiac electrophysiological examination to understand the target point where the arrhythmia occurs; 2. choose to puncture the femoral vein or femoral artery after understanding the target point and place special electrodes into the target location; 3. give appropriate radiofrequency treatment according to the type of arrhythmia to ablate the target point and eliminate the ectopic point or focal point where the arrhythmia occurs; 4. verify whether the surgery is successful after the surgery is done. If the arrhythmia is induced by intracardiac electrodes during the procedure and no arrhythmia occurs again, the procedure is considered successful and RF ablation is completed. Complications of radiofrequency ablation, such as embolism and cardiac tamponade, have an incidence of only about 1%, and the incidence of arteriovenous fistula is only 0.04%. In fact, the incidence of these complications or adverse events is very low, so radiofrequency ablation is a relatively safe procedure and a means to effectively treat arrhythmias.
