Abstract: Проводят одновременную синхронную запись ЭКГ и пневмограммы. Рассчитывают моду гистограммы длительности дыхательных циклов. Проводят графическое наложение на нее спектрограммы высокочастотной компоненты ритма сердца. По положению пика максимальной мощности спектра уточняют границу низкочастотной компоненты сердечного ритма. Если пик максимальной мощности высокочастотной компоненты ритма сердца отличается по частоте от моды частоты дыхания более чем на 0,06 Гц, диагностируют десинхронизацию дыхательного и сосудодвигательного центров вегетативной нервной системы. Если же повышение мощности низкочастотной компоненты сопровождается изменением паттерна дыхания, диагностируют наличие у пациента состояния психоэмоционального напряжения. Применение предлагаемого способа позволяет сократить время диагностики, уточнить границы между низко- и высокочастотными диапазонами сердечного ритма, диагностировать десинхронизацию дыхательного и сосудодвигательного центров вегетативной нервной системы, определять наличие психоэмоционального напряжения. 13 ил., 1 табл.
