intact animal to the cellular, subcellular, and molecular levels. It is published 12 times a year (monthly) by the American lymphatics, including experimental and theoretical studies of cardiovascular function at all levels of organization ranging from the publishes original investigations on the physiology of the heart, blood vessels, and AJP-Heart and Circulatory Physiology
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...
متن کاملNocturnal evolution of heart rate variability indices in sleep apnea
Heart rate variability (HRV) is a valuable clinical tool in diagnosing multiple diseases. This paper presents the results of a spectral HRV analysis conducted with 46 patients. HRV indices for the whole night show differences among patients with severe and mild apnea, and healthy subjects. These differences also appear when performing the analysis over 5-min intervals, regarding apneas being pr...
متن کاملHeart rate turbulence in patients with obstructive sleep apnea syndrome.
BACKGROUND Heart rate turbulence (HRT) assessment is used as noninvasive method based on physiological sinus node response to the premature ventricular beat. Blunted HRT may indicate the autonomic nervous system impairment and can be helpful in identifying high-risk patients. Obstructive sleep apnea syndrome (OSAS) leads to cardiovascular complications. Autonomic nervous system and baroreflex d...
