Hyperthyroidism atrial fibrillation refers to the effect of thyrotoxicosis on the heart, which can largely disappear when the thyrotoxicosis is corrected. The treatment of hyperthyroidism includes medication, radioiodine therapy, surgery and other treatments. 1. Medication: The medication includes methimazole, propylthiouracil, etc. Medication is the basic treatment of hyperthyroidism, and it can also be used in the preparatory stage of surgery and radioiodine treatment. The use of medication should be under the guidance of a doctor. 2. Radioiodine therapy: Treatment with iodine 131 destroys thyroid tissue and can reduce thyroid hormone production. 3. Surgery: Subtotal thyroidectomy is often used. 4. Other treatments: These include reducing iodine intake and using beta-blockers such as propranolol. In the case of hyperthyroidism atrial fibrillation, please go to the hospital in time for treatment.
