Determinants of Heart-rate Variability in Obstructive Sleep Apnea Syndrome (osas) during Wakefulness and Sleep Model-based Ass
Word Count=200) Heart-rate variability (HRV) is mediated by at least three primary mechanisms: (a) vagal feedback from pulmonary stretch receptors ("PSR"); (b) central medullary coupling between respiratory and cardiovagal neurons ("RCC"); and (c) arterial baroreflex-induced fluctuations ("ABR"). We employed a noninvasive experimental protocol in conjunction with a minimal model to determine ho...

Heart rate variability (HRV) is mediated by at least three primary mechanisms: 1) vagal feedback from pulmonary stretch receptors (PSR), 2) central medullary coupling between respiratory and cardiovagal neurons (RCC), and 3) arterial baroreflex (ABR)-induced fluctuations. We employed a noninvasive experimental protocol in conjunction with a minimal model to determine how these sources of HRV ar...
متن کاملApert Syndrome with Obstructive Sleep Apnea: A Case Report
Apert syndrome is a rare kind of craniosynostosis which is identified with fusion of cranial sutures during prematurity period and causes physical and intellectual disorders in younger ages. These patients may show symptoms of obstructive sleep apnea due to abnormal craniofacial shape. This article introduces a patient with Apert syndrome, with apnea symptoms, cyanosis, snoring, restlessness, n...
متن کاملObstructive sleep apnea syndrome and non-arteritic anterior ischemic optic neuropathy: a case control study
Background: Sleep apnea is temporary cessation or absence of breathing during sleep. Significant increase in blood pressure is clinically seen in apneic episodes. The aim of this study was to examine sleep apnea syndrome as a risk factor for non- arthritic anterior ischemic optic neuropathy (NAION) in a case control study. Methods: Nineteen NAION patients (9 men and 10 women) and 31 age and ...
متن کاملSpectral indices of cardiac autonomic function in obstructive sleep apnea.
Spectral analysis of heart rate variability (HRV) is useful as a noninvasive means of assessing autonomic function in patients with obstructive sleep apnea (OSA). However, standard spectral measures, such as the ratio of low-frequency to high-frequency power (LHR) and normalized high-frequency power (NHFP), can be confounded by the abnormal breathing patterns that occur during sleep. To circumv...
