title: [Hyperthyroidism caused by amiodarone. Apropos of 4 clinical cases].
abstract: The authors report four new cases of hyperthyroidism associated with prolonged treatment with amiodarone. Massive doses of beta-blockers were required to deal with the severely disordered rhythm in one of the patients. Amiodarone, which is an effective treatment for angina, is not free from risk, even at the doses which are currently accepted. Hyperthyroidism, which may occur even in patients who have had no past history of any thyroid troupble at all, remains a most unusual complication.
