[Amiodarone and hyperthyroidism].

22 cases of hyperthyroidism occurring during or following treatment with amiodarone are reported and compared with more than 15 cases in the literature. The specific clinical features of these cases of hyperthyroidism are presented and the problems in interpretation of the laboratory thyroid function tests are discussed. A study of the course of these cases reveals a number of prognostic factors. Finally, the authors describe the practical management of this form of hyperthyroidism.
