RT Journal Article SR Electronic T1 Carbamazepine, serum thyroid hormones and myocardial function in epileptic patients. JF Journal of Neurology, Neurosurgery & Psychiatry JO J Neurol Neurosurg Psychiatry FD BMJ Publishing Group Ltd SP 710 OP 712 DO 10.1136/jnnp.56.6.710 VO 56 IS 6 A1 J I Isojärvi A1 K E Airaksinen A1 M Repo A1 A J Pakarinen A1 P Salmela A1 V V Myllylä YR 1993 UL http://jnnp.bmj.com/content/56/6/710.abstract AB 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.
