Association of risk factors with increased pulse wave velocity detected by a novel method using dual-channel photoplethysmography.

Background: Pulse wave velocity (PWV) is correlated with cardiovascular risk. This study presents a new method for measuring the arterial PWV by simultaneously recording the digital volume pulse through the finger and the toe by way of dual-channel photoplethysmography (PPG).

Methods: In this study, 100 asymptomatic subjects (54 men and 46 women, 19 to 64 years of age) were enrolled.
