TY - JOUR A2 - Boyanov, Mihail A. AU - Eom, Young Sil AU - Oh, Pyung Chun PY - 2020 DA - 2020/12/15 TI - Graves’ Disease Presenting with Complete Atrioventricular Block SP - 6656875 VL - 2020 AB - Hyperthyroidism commonly causes tachyarrhythmias such as sinus tachycardia and atrial fibrillation. Impaired atrioventricular conduction is a very rare complication of hyperthyroidism. We report a case of a patient with hyperthyroidism due to Graves’ disease presenting with syncope and complete atrioventricular block. Because lack of awareness of atypical presentation in patients with hyperthyroidism may delay diagnosis and treatment, the recognition that hyperthyroidism can be one of the reversible causes of complete atrioventricular block is important.
