Obstructive sleep apnea (OSA) is a serious sleep disorder, which leads to changes in
autonomic nerve function and increases the risk of cardiovascular disease. Heart rate …

Obstructive sleep apnea (OSA) syndrome is a common sleep disorder. As an alternative to
polysomnography (PSG) for OSA screening, the current automatic OSA detection methods …

Sample entropy, a nonlinear signal processing approach, was used as a measure of signal
complexity to evaluate the cyclic behavior of heart rate variability (HRV) in obstructive sleep …

Obstructive sleep apnea (OSA) is a common sleep disorder that is often associated with
reduced heart rate variability (HRV), thus reflecting modulation of the autonomic system …

Ever since the use of heart rate variability (HRV) as a tool for quantification of autonomic
nervous system dynamics has become popular, the interest in exploring the hidden …

Heart rate variability (HRV) is a widely used measure for the variation of the heartbeat
intervals controlled by the autonomic nervous system (ANS), which is primarily obtained by …

Obstructive sleep apnea (OSA) is an independent cardiovascular risk factor to which
autonomic nervous dysfunction has been reported to be an important contributor. Ninety …

Obstructive sleep apnea (OSA) is associated with reduced heart rate variability (HRV) and
autonomic nervous system dysfunction. Sample entropy (SampEn) is commonly used for …

Obstructive sleep apnea (OSA) is a fatal respiratory disease occurring in sleep. OSA can
induce declined heart rate variability (HRV) and was reported to have autonomic nerve …

In this paper, novel heart rate variability (HRV) indices were extracted for the autonomic
nervous system (ANS) activity assessment in congestive heart failure (CHF). It has been …
