Heart rate variability in patients with obstructive sleep apnea.
Several studies found that breathing abnormalities like OSA or Cheyne-Stokes ventilation are related to periodic changes in heart rate [1,2]. The influences of OSA on HRV analyzed by power spectral analysis have not been investigated until now. The purpose of this study was, therefore, to assess changes in the power spectrum of HRV during episodes of OSA as compared to a normal breathing patter...
متن کاملthe relationship between severity of obstructive sleep apnea and heart rate variability
background and objective: obstructive sleep apnea syndrome (osas) is a prevalent disease in adults. limited evidence regarding the effect of severity of sleep apnea and depression on heart rate variability (hrv) indices exists. hence, we decided to focus on the association between hrv and severity of osas based on depression score. materials and methods: a total of 193 patients with confirmed o...

متن کاملDeterminants of heart rate variability in obstructive sleep apnea syndrome during wakefulness and sleep.
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 کاملRespiratory rate variability in sleeping adults without obstructive sleep apnea
Characterizing respiratory rate variability (RRV) in humans during sleep is challenging, since it requires the analysis of respiratory signals over a period of several hours. These signals are easily distorted by movement and volitional inputs. We applied the method of spectral analysis to the nasal pressure transducer signal in 38 adults with no obstructive sleep apnea, defined by an apnea-hyp...
