Monitoring and assessment for obstructive sleep apnea
FlexMat, EarlyView.This review systematically classifies Obstructive Sleep Apnea (OSA) monitoring indicators into three categories: physical, biochemical, and electrophysiological indicators, and lists several methods for each category. Abstract Obstructive sleep apnea (OSA) is a common chronic sleep‐disordered breathing disease characterized by recurrent upper airway ...

Sleep Research, EarlyView.Abstract Polysomnography (PSG), the reference standard for sleep assessment, has limited scalability for large‐scale screening, driving the development of wearable and unobtrusive monitors. However, the physiological signals these devices capture are physiologically correlated with PSG channels but are not completely equivalent.

Fragmented QRS Complex: A Novel Marker of Cardiovascular Disease [PDF]
Clinical Cardiology, 2010 AbstractQRS complex fragmentation, defined as changes in QRS morphology with different RSR′ patterns: additional R waves, notched S wave, or > 1R′ wave, has recently been linked with various cardiac conditions and even been postulated to be predictive of outcomes in certain pathologies.

CAAI Transactions on Intelligence Technology, EarlyView.Abstract Abnormalities in the heart's rhythm, known as arrhythmias, pose a significant threat to global health, often leading to severe cardiac conditions and sudden cardiac deaths. Therefore, early and accurate detection of arrhythmias is crucial for timely intervention and potentially life‐saving treatment.

Profiling the sleep architecture of ageing adults using a seven‐state continuous‐time Markov model
Journal of Sleep Research, Volume 34, Issue 2, April 2025.Summary Sleep is a complex biological process regulated by networks of neurons and environmental factors. As one falls asleep, neurotransmitters from sleep–wake regulating neurones work in synergy to control the switching of different sleep states throughout the night. As sleep disorders or underlying neuropathology can manifest as irregular switching,

Annals of Noninvasive Electrocardiology, 2021 Background A novel metric called Layered Symbolic Decomposition frequency (LSDf) has been shown to be an independent predictor of ventricular arrhythmia and mortality in patients receiving implantable cardioverter‐defibrillator (ICD) devices.
