Subclinical hyperthy: A low TSH with a normal T4 and no symptoms is usually subclinical hyperthyroidism. She may have a multinodular goiter that is autonomously functioning, or very early graves disease. A T3 (liothyronine) level and free T4 level should be checked. There is a higher risk of developing atrial fibrillation despite the normal T4 level, but many endocrinologists would just follow her levels for progression.
