Contactless Measurement of Heart Rate, Heart Rate Variability and Breathing Rate Using Remote Photoplethysmography

"Resting heart rate (HR), heart rate variability (HRV) and breathing rate (BR) will be measured (estimated) with the use of remote photoplethysmography (1-minute face video analysis with Shen.AI Vitals software).~Reference measurements will be taken simultaneously (chest ECG for the calculation of HR and HRV; impedance pneumography for BR)."
