Heart Rate Estimation From Remote Photoplethysmography Based on Light-Weight U-Net and Attention Modules

IEEE Access, 2023
Cardiac signals are frequently used in disease and emotion analyses. However, current measurement methods mostly require direct contact. Remote photoplethysmography (rPPG) has been proposed in recent years which measures minute variations in color on the

Remote Monitoring With a Reusable Device Upon Implementation on a Surgical Department (REQUEST Trial)

World Journal of Surgery, EarlyView.
Continuous monitoring of vital signs using wearable devices may improve early detection of postoperative complications and reduce nursing workload. Evidence from real‐world clinical implementation remains limited. This study aimed to answer the question: Does the implementation of wearable monitoring in surgical wards reduce nursing workload and is it ...

Sleep and cardiac autonomic modulation in older adults: Insights from an at‐home study with auditory deep sleep stimulation

Journal of Sleep Research, Volume 34, Issue 2, April 2025.
Summary The autonomic nervous system regulates cardiovascular activity during sleep, likely impacting cardiovascular health. Aging, a primary cardiovascular risk factor, is associated with cardiac autonomic disbalance and diminished sleep slow waves. Therefore, slow waves may be linked to aging, autonomic activity and cardiovascular health. However, it
