Non-invasive method for measuring local pulse wave velocity in arteries: part II

摘要

The application of the DU-loop method seems to be very promising. Apart from the simple mathematical formula used and the few parameters necessary to its application (only the flow velocity and diameter data are necessary), the method which can be atraumatic provides an exact value of the local PWV with minor error. From our experiment and simulation, there is a very distinct linear portion of the curve corresponding to the reflection free period of the cycle.
