This paper is concerned with a new approach for the estimation of arterial stiffness from the digital volume pulse (DVP). From the previous studies, it is well-known that arterial stiffness is a reasonable indicator of cardiovascular events and thus can be used as a prognostic factor of cardiovascular diseases. To evaluate arterial stiffness, various diagnostic techniques, such as the pulse wave velocity...
Many previous studies suggested that the digital volume pulse (DVP) can be used to estimate arterial stiffness. The DVP waveform can be rapidly acquired by measuring reflection or absorption of red light (or infrared light) across the photoplehtysmography (PPG). Because of the nature of its measuring principle, the DVP is often contaminated by noise from light sources, such as sunlight, and disturbances...
Over the past few years, a considerable number of studies have focused on estimation of arterial stiffness by using a digital volume pulse (DVP). This can generally be achieved by a linear regression analysis with several pulse parameters. Among various pulse parameters, since time-related pulse parameters, such as reflected wave arrival time, are varied with pulse rate, it can provide incorrectly...
