Features of vegetative regulation and structurally functional parameters of heart at toxic goiter in a month after thyroidectomy
Research objective was studying of vegetative regulation of heart activity and an assessment of structurally functional characteristics in case of diffusion toxic craw in early postoperative period against replaceable therapy with levothyroxine. 102 patients with a diffusion toxic craw in a month after a total thyroidectomy aged from 18 till 55 years were surveyed. On initial vegetative balance the surveyed were divided into 3 groups (simpathicotoniya, eutoniya, vagotonia). It is established that the increased frequency of heart contractions and low rate variability of heart rhythm in the early postoperative period against a noncompensated postoperative hypothyroidism are caused by simpathicotonia. During compensation of a postoperative hypothyroidism a positive dynamics of heart rhythm variability is caused by decreased simpatic influences on heart work. Patients with vegetative balance before operation had no violations of vegetative regulation of heart activity after a thyreoidectomia against replaceable therapy of compensated postoperative hypothyroidism with levothiroxine. At violations of vegetative regulation of a heart rate against dynamically changing thyroid status before and after a thyreoidectomia the structurally functional changes of heart, as well as arrhythmias were not revealed.
