For patients with paroxysmal atrial fibrillation, it is recommended that they be treated with medication first, and then radiofrequency ablation if medication is ineffective. Radiofrequency ablation is an invasive surgical procedure, and any surgical procedure carries a certain amount of risk, and radiofrequency ablation is no exception. However, radiofrequency ablation is also relatively safe overall, with fewer patients experiencing serious postoperative complications. Possible complications of radiofrequency ablation include pericardial effusion, cardiac tamponade, atrioventricular block, myocardial infarction, and aortic regurgitation. Although the chance of these complications is low, the possibility of their occurrence exists. For patients with paroxysmal atrial fibrillation, medication should be used to control the symptoms and regulate the heart rate, and radiofrequency ablation should be considered after medication is ineffective. Patients with paroxysmal atrial fibrillation should go to the hospital in time, choose the appropriate treatment plan under the guidance of the doctor, and carry out standardized treatment.
