| Summary: | Local pulse wave velocity (PWV) is one of important
indicators of artery wall's elastic properties. This paper describes a
non-invasive method of examinations of local PWV on the basis of ultrasonic
blood flow velocity measurements at two points, several centimetres along the
common carotid artery (CCA). This velocity was compared with values of PWV
calculated on the basis of measurement of distensibility coefficient DC. The
examinations were carried out on the group of 12 healthy volunteers ranging in
age from 22 to 68 years (mean 39[ampersand]plusmn;16 years). Mean value of local PWV for
the examined group was 5.1[ampersand]plusmn;1.09 m/s. This velocity was linearly
correlated (r = 0.9807) with the PWV examined on the basis of distensibility
coefficient DC, the mean value of which was 6.14[ampersand]plusmn;1.29 m/s. |
