The PWV measurements by the in vitro model.

Notes: PWVA-B, pulse wave velocity between point A and B; ΔdA-B, the distance between A and B; ΔtA, the transit time between the transducer and point A; ΔtB, the transit time between the transducer and point B; PWVM, local pulse wave velocity at the middle of point A and B; ΔdM, the distance of the chosen segment at the middle of point A and B; ΔtM, transit time of the pulse wave at the middle segment.
