Обследовано 65 больных ГБ, средний возраст — 53,7 ± 10,1 года; из них — 26 человек с СОАС легкой и средней степени тяжести (группа 1) и 39 человек с тяжелым СОАС (группа 2). В комплекс обследования входило определение антропометрических показателей, проведение кардиопульмонального мониторирования (КПМ), анализ вариабельности ритма сердца (ВРС) в покое и при проведении ОСП.</p></sec><sec><title>Результаты</title><p>Результаты. В группе 1 выявлено преобладание симпатических влияний в регуляции сердечного ритма, а также значительный вклад волн очень низкой частоты (VLF — very low frequency) в общий спектр. Основные показатели КПМ в этой группе не влияли на показатели ВРС. В группе 2 выраженность нарушений дыхания во время сна прямо коррелировала с увеличением доли волн низкой частоты и коэффициента LF/HF, а также снижением доли волн высокой частоты (HF — high frequency). При проведении ОСП в группе 1 увеличивалась общая мощность спектра за счет большего вклада волн низкой частоты (LF — low frequency) и VLF-волн. Коэффициент LF/HF возрастал при проведении ОСП. В группе 2 парадоксально увеличивалась доля HF-волн в регуляции сердечного ритма. Коэффициент LF/HF уменьшался.</p></sec><sec><title>Выводы</title><p>Выводы. Выявлено нарушение вегетативной регуляции сердечного ритма у пациентов с СОАС. С увеличением степени тяжести СОАС происходила избыточная симпатическая активация, проявляющаяся увеличением доли VLF и LF-волн в сердечном ритме.</p></sec></abstract><trans-abstract xml:lang="en"><sec><title>Objective</title><p>Objective. To analyze peculiarities of heart rate autonomic regulation in patients with hypertension and obstructive sleep apnea (OSA) at rest and during active orthostatic test (AOT).</p></sec><sec><title>Design and methods</title><p>Design and methods. The study involved 65 patients, average age — 53,7 ± 10,1 years. The complex examination included anthropometric parameters measurement, cardiopulmonary monitoring (CPM), and analysis of heart rate variability (HRV) at rest and during the AOT.</p></sec><sec><title>Results</title><p>Results. The group 1 included 26 people with mild-to-moderate OSA, the group 2 consisted of 39 patients with severe OSA. In group 1 sympathetic influences on the heart rate regulation were predominant, and very low frequency (VLF) waves made a significant contribution in the overall spectrum. Key indicators of the CPM had no effects on HRV in group 1. In group 2, the severity of respiratory disorders directly affected the heart rate: low frequency (LF) waves and the LF/HF index, while high frequency (HF) waves reduced along with the increase in OSA severity. In group 1, the total capacity of the spectrum increased due to a larger contribution of LF-waves and VLF-waves during the AOT. The LF/HF index increased during the AOT. In group 2, there was a paradoxical increase in HF-waves, and a decrease in LF/HF index.</p></sec><sec><title>Conclusions</title><p>Conclusions. The autonomic regulation of the heart rate is disturbed in hypertensive patients with OSA. Excessive sympathetic activation occurs as OSA severity increases, manifesting as the rise of VLF and LF-waves proportion and being the most profound in patients with severe OSA.</p></sec></trans-abstract><kwd-group xml:lang="ru"><kwd>синдром обструктивного апноэ сна</kwd><kwd>вегетативная нервная система</kwd><kwd>гипертоническая болезнь</kwd><kwd>вариабельность ритма сердца</kwd><kwd>ортостатическая проба</kwd></kwd-group><kwd-group xml:lang="en"><kwd>obstructive sleep apnea syndrome</kwd><kwd>hypertension</kwd><kwd>heart rate variability</kwd></kwd-group></article-meta></front><back><ref-list><title>References</title><ref id="cit1"><label>1</label><citation-alternatives><mixed-citation xml:lang="ru">Punjabi N.M.
