Background—Enhanced nocturnal heart rate variability (HRV) has been evoked in sleep-
related breathing disorders. However, its capacity to detect obstructive sleep apnea …

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

Background—Despite the adverse cardiovascular consequences of obstructive sleep
apnea, the majority of patients remain undiagnosed. To explore an efficient ECG-based …

Background: Cyclic variation of the heart rate is observed during apneic spells in obstructive
sleep apnea (OSA). We hypothesized that autonomic changes would affect frequency …

Low long-term heart rate variability (HRV), often observed in obstructive sleep apnea (OSA)
patients, is a known risk factor for cardiovascular diseases. However, it is unclear how the …

Heart rate fluctuations are a typical finding during obstructive sleep apnoea, characterised
by bradycardia during the apnoeic phase and tachycardia at the restoration of ventilation. In …

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

The sleep apnoea/hypopnoea syndrome (SAHS) elicits a unique heart rate rhythm that may
provide the basis for an effective screening tool. The study uses the receiver operator …

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 …

Heart rate variability (HRV) can reflect the changes in the autonomic nervous system (ANS)
that are affected by apnea or hypopnea events among patients with obstructive sleep apnea …
