A new statistical phase offset technique for the calculation of pulse wave velocity

Pulmonary blood pressure measurements were collected from 5 clinically healthy horses. Pulse wave velocity (PWV) values were calculated using five techniques, four existing (minimum foot-to-foot, F2F; maximum 1st derivative, M1D; maximum 2nd derivative, M2D; and cross correlation, CC) and the new statistical phase offset technique (SPO). The SPO technique was also applied to systolic (SPO-S), diastolic (SPO-D) and full wave (SPO-FW) data. The reliability of each analysis technique was determined using the consistency of calculated PWV values.
