FEATURES OF VEGETATIVE REGULATION AND STRUCTURAL FUNCTIONAL PARAMETERS OF HEART IN DIFFUSION TOXIC CRAW THREE MONTHS LATER AFTER THYREOIDECTOMIA

Abstract

The aim of research was to study vegetative regulation of heart function and to assess structural functional characteristics of heart in diffusion toxic craw at the early postoperative period associated with replaceable Levothyroxine therapy. 102 patients aged 18-55 with diffusion toxic craw were examined three months later after total thyreoidectomia. According to the initial vegetative balance, the examined were divided into 3 groups (sympathicotonia, eitonia, parasimpaticotonia). The study determined the general heart rate variability, frequency of heartbeats, first of all, at the expense of decrease in sympathetic effect on heart function in 36.3 % patients 3 months after the operation in compensation of postoperative hypothyroidism associated with replaceable Levothyroxine therapy. Neither disturbances of vegetative regulation of heart rate associated with dynamically changing thyrеoid status before and after thyreoidectomia of structurally functional changes of heart, nor arrhythmia were not revealed. The patients with vegetative balance before the operation had no disturbances of vegetative regulation of heart function after thyreoidectomia.
