Radiofrequency ablation of atrial fibrillation has some risk, but the risk is not considered significant. Atrial fibrillation is a type of arrhythmia. It may be associated with alcohol consumption, coronary atherosclerotic heart disease, hypertensive heart disease, infective endocarditis and other diseases. Radiofrequency ablation for atrial fibrillation is performed by inserting electrodes into the heart lesion site through veins such as the femoral vein, internal jugular vein, and subclavian vein, and utilizing the electrodes at the tip of the catheter to produce an electrothermal effect within the cardiomyopathic cells to cause necrosis and treat atrial fibrillation. The current technology of radiofrequency ablation surgery is relatively mature, but it may also lead to atrioventricular block, thrombosis, cardiac tamponade, esophageal mucosal injury, local vascular bleeding and other risks. Therefore, radiofrequency ablation surgery for atrial fibrillation is generally not very risky, and it is recommended to go to a regular hospital for treatment.
