Video capillaroscopy clarifies mechanism of the photoplethysmographic waveform appearance
Abstract Photoplethysmography (PPG) devices are widely used in clinical practice but the origin of PPG signal is still under debating. The classical theory assumes that the PPG waveform stems from variations of blood volume in pulsating arteries. In this research we analysed high-speed video recordi...
