[Autonomic nervous system function of euthyroid and thyrotoxic goiter patients].

Variation pulsometry, a method of mathematical analysis of the cardiac rhythm, was used to assess function of the autonomic nervous system in patients with euthyroid and thyrotoxic goiter. Simultaneously orthostatic tests for a selective effect on parts of the autonomic nervous system were done. A total of 46 patients were examined: 16 with nodular forms of euthyroid goiter and 30 with thyrotoxic goiter III. In the patients with euthyroid goiter a moderate degree and in the patients with thyrotoxicosis a pronounced degree of tension of both parts of the regulation system were revealed. At the visceropathic stage of thyrotoxicosis, intra-endocrine interrelationships with the blockade of the sympathetic part of the autonomic nervous system are changed that can be of importance for working out medicamentous preoperative preparation of patients.
