[Second degree atrioventricular block in Graves' disease].
Cardiac tachyarrhythmias are common in thyrotoxicosis. We report an uncommon case of a 53-year-old woman with Grave's disease who developed second degree A-V block while euthyroid on propylthiouracil. The most likely mechanism is an autoimmune response causing infiltration of the cardiac conduction pathways.
