Comparison of Multi-Wavelength PPG at Wrist and Finger for Non-Invasive Vascular Aging Assessment Using APG Analysis
Vascular aging, characterized by progressive arterial stiffening, is an independent predictor of cardiovascular risk. Acceleration plethysmography, which is obtained from the second derivative of the photoplethysmographic signal, allows for the non-invasive extraction of vascular aging indices from five fiducial points...
