Целью настоящей работы является оценка возможности использования показателей вариабельности сердечного ритма для динамического контроля функции щитовидной железы после радиойодтерапии. Проведено 114 исследований уровня св. Т4 с параллельной оценкой параметров вариабельности сердечного ритма в процессе лечения (до назначения                   131I, через 1, 3, 6, 12 мес) у 77 больных. Из всех показателей были выбраны 2, наиболее тесно коррелирующие с уровнем св. Т4 и относительно независимые между собой. Вся выборка случайным образом была разделена на обучающую (86 исследований) и тестовую (28 исследований). Методом опорных векторов на обучающей выборке найдено решающее правило: f(HR,SDNN) = 0,995 lg(HR) – 0,104 lg(SDNN) – 1,703, где f – показатель функции щитовидной железы; HR – средняя частота сердечных сокращений за 5-минутную запись ЭКГ; SDNN – стандартное отклонение интервалов R-R на зарегистрированной записи ЭКГ; 0,995, 0,104 и 1,703 – поправочные коэффициенты. При f &gt;0, рассчитанным согласно решающему правилу, у исследуемого имеет место тиреотоксикоз; при f &lt;0 тиреотоксикоза не наблюдается. При анализе точности диагностического метода на тестовой выборке были получены следующие результаты: диагностическая чувствительность составила 71%, диагностическая специфичность составила 79%. Таким образом, предлагаемый метод позволяет с высокой вероятностью предполагать ликвидацию тиреотоксикоза или развитие рецидива заболевания после радиойодтерапии. Его использование может оптимизировать контроль функции щитовидной железы, отказавшись от фиксированных сроков определения гормонов.</p></abstract><trans-abstract xml:lang="en"><p>Time of the transformation to the euthyroid condition after radioiodine therapy of Grave’s disease is individual and deviates from weeks to months, what requires frequent hormones control. The aim of this study was the assessment of possibility to use HRV parameters in dynamic control after the radioiodine therapy. 77 patients were examined with 114 fT4 measurement and HRV parameters recording (before radioiodine administration and in 1, 3, 6, 12 months after). From HRV parameters two were chosen as characterizing the closest correlation with fT4 and relatively independent from each other. The whole sample was divided into the teaching set (86 measurements) and the test set (28 measurements). The decision rule was found by support vector machine in the teaching set asf(HR,SDNN) = 0.995 lg(HR) – 0.104 lg(SDNN) – 1.703, where f is the indicator of the thyroid gland function, HR – heart rate during 5-minute ECG recording; SDNN – standard deviation of RR intervals; 0.995 , 0.104 and 1.703 – correcting coefficients. If f &gt; 0, the thyrotoxicosis takes place in a patient. If f &lt; 0 – there is no thyrotoxicosis. The analysis of diagnostic method precision in testing set gave the following results: diagnostic sensitivity was 71%, the diagnostic specificity 79%. This method can predict thyrotoxicosis elimination or relapse with high possibility. Its use can optimize thyroid function control and refuse from fixed time hormone measurement.</p></trans-abstract></article-meta></front><back><ref-list><title>References</title><ref id="cit1"><label>1</label><citation-alternatives><mixed-citation xml:lang="ru">Баевский Р.М. и др.
