In the past, it was thought that atrial fibrillation could not be cured, and medication was taken to maintain it, hoping that it would be delayed as long as possible and not become worse. But in the past, medication could not cure atrial fibrillation, and prolonged medication had certain toxic side effects. Catheter radiofrequency ablation can cure atrial fibrillation. Catheter radiofrequency ablation? How is it treated? The procedure is like an infusion, in which an electrode catheter is sent into the heart through a vein or arterial blood vessel, and radiofrequency current is conducted through the catheter into the heart tissue, causing the local tissue temperature to rise and producing local coagulative necrosis, thus achieving the goal of blocking the abnormal conduction bundle and eradicating tachycardia, which is called catheter radiofrequency ablation. The radiofrequency current introduced to the heart through the cardiac catheter is only 1-3mm in extent, so it will not cause any harm to the human body. What are the risks of the procedure? Catheter ablation of atrial fibrillation is a complex procedure and patients should visit an experienced treatment center whenever possible. Like any other procedure, catheter ablation for atrial fibrillation is not absolutely safe, but safety is relatively assured at an experienced treatment center.
