Case in brief
Two patients presented with new-onset atrial fibrillation (AF) as the initial manifestation of hyperthyroidism. The first case involved rapid AF due to Graves' disease, while the second case was attributed to a solitary toxic adenoma. Both cases highlight the need for thyroid evaluation in patients with unexplained AF, leading to appropriate management of the underlying hyperthyroid condition.
Diagnostic / clinical pearl
Clinicians should consider hyperthyroidism as a potential cause of new-onset atrial fibrillation, prompting thyroid function tests in such cases.
