Impact of eight weeks of repeated ischaemic preconditioning on brachial artery and cutaneous microcirculatory function in healthy males [PDF]

, 2014
Background Ischaemic preconditioning has well-established cardiac and vascular protective effects. Short interventions (one week) of daily ischaemic preconditioning episodes improve conduit and microcirculatory function.

Remote Photoplethysmography using Commercially Available Webcams

, 2021
Photoplethysmography (PPG) is a non-invasive method used to measure heart rate by utilizing light. On the other hand, Remote photoplethysmography (rPPG) is a cutting-edge technology that enables contactless monitoring of human cardiac activities. It achieves this by detecting the pulse-induced subtle color variations on the human skin surface using a ...

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
