Abstract:
Pulse wave velocity (PWV) is a measure of arterial stiffness. A strong correlation between PWV and cardiovascular events that cause mortality, was recognized. The foot-to-foot (f-t-f) method is a standard techniques used for the determination of arterial PWV. This technique offers an estimation of the regional wave speed. F-t-f methods usually require longer vessels to allow the measurements at two sites. In this work, we present a mathematical description of a new method for the determination of the local PWV; Diameter Velocity loop (Dvcl - loop). The method only requires the measurements of centre line velocity and diameter which can be obtained non-invasively. We conclude that the Dvcl - loop method provides a reliable local pulse wave velocity and has the merits of using non-invasive parameters.
