Insights
Hyperthyroidism, often causing rapid heart rhythms, can rarely lead to complete atrioventricular block. Recognizing this rare complication is crucial for timely diagnosis and treatment of Graves
Area of Science:
- Cardiology
- Endocrinology
- Internal Medicine
Background:
- Hyperthyroidism is a common endocrine disorder.
- Tachyarrhythmias like sinus tachycardia and atrial fibrillation are frequent complications.
- Impaired atrioventricular conduction is an exceptionally rare manifestation.
Abstract:
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.
