Obstructive sleep apnea is a highly prevalent sleep‐related breathing disorder, resulting in a
disturbed breathing pattern, changes in blood gases, abnormal autonomic regulation …

Obstructive Sleep Apnea is a common respiratory disorder characterized by recurrent
nocturnal episodes of normal breathing interruption due to upper airway total or partial …

Obstructive sleep apnea (OSA), a heterogeneous and multifactorial sleep related breathing
disorder with high prevalence, is a recognized risk factor for cardiovascular morbidity and …

Obstructive sleep apnea is a common sleep breathing disorder related to autonomic
nervous function disturbances. Heart rate variability is an important non‐invasive indicator of …

Obstructive sleep apnea (OSA) is a highly prevalent condition, resulting in recurrent hypoxic
events, sleep arousal, and daytime sleepiness. Patients with OSA are at an increased risk of …

Abstract Study Objectives Patients with obstructive sleep apnea (OSA) exhibit
heterogeneous heart rate variability (HRV) during wakefulness and sleep. We investigated …

Here we discuss the current perspectives of comprehensive heart rate variability (HRV)
analysis in electrocardiogram (ECG) signals as a non-invasive and reliable measure to …

Background Obstructive sleep apnoea (OSA) results in sympathetic overdrive. Increased
nocturnal heart rate variability (HRV) is a surrogate marker of autonomic disturbance. The …

Obstructive sleep apnea (OSA) is a heterogenous chronic disorder causing hypoxemia,
excessive daytime sleepiness, non-refreshing sleep, nocturia, morning headache, irritability …

There is now a large body of literature indicating that daytime sleepiness is only one clinical
aspect of the obstructive sleep apnea syndrome (OSAS) and that OSAS is linked with …
