The PWV measurements by the in vitro model.

<p>Notes: PWV<sub>A-B</sub>, pulse wave velocity between point A and B; Δd<sub>A-B</sub>, the distance between A and B; Δt<sub>A</sub>, the transit time between the transducer and point A; Δt<sub>B</sub>, the transit time between the transducer and point B; PWV<sub>M</sub>, local pulse wave velocity at the middle of point A and B; Δd<sub>M</sub>, the distance of the chosen segment at the middle of point A and B; Δt<sub>M</sub>, transit time of the pulse wave at the middle segment.</p><p>The PWV measurements by the in vitro model.</p>
