Evaluation of the Possible Use of PPG Waveform Features Measured at Low Sampling Rate
IEEE Access, 2019 To date, the applications of photoplethysmograms in the estimation of cuff-less blood pressure, arteriosclerosis, and so on have been studied. Photoplethysmogram waveform features have often been used to estimate the target volumes. For these estimations,

Standard Terminologies for Photoplethysmogram Signals [PDF]
Current Cardiology Reviews, 2012 Photoplethysmography is one of the optical techniques has been developed for experimental use in vascular disease. It has several advantages over other traditional experimental approaches. Because of its non-invasive, safe, costeffective and easy-to-use properties, it is considered as a useful diagnostic tool.
