Abstract
Serum thyroid hormone and thyrotropin levels were assayed and the myocardial function was evaluated by measuring systolic time intervals both in 30 patients with epilepsy on long-term carbamazepine monotherapy and in 19 healthy volunteers. Serum thyroxine, free thyroxine and triiodothyronine levels were significantly lower (p < 0.001) in the patient group than in the control group and systolic time intervals were similar in both groups.
