Objectives: Examine the effect of erroneous estimation of wave speed (C) on the magnitude and time of the separated pressure (P) and velocity (U) in arteries. Methods: Pressure and flow were measured in the aorta of 11 dogs and C has been determined using the PU-loop technique. The waves were separated...

Background: Aortic pulse wave velocity (PWV) is an independent predictor of cardiovascular risk. Phase contrast magnetic resonance imaging (PCMRI) is a recent technique that allows PWV to be measured along the entire aorta (aPWVMRI), as well as in regions of interest. The aim of this study was to test...

Arterial pressure and flow waves travel and are reflected. Waveform analysis and wave separation gave insight into these phenomena and parameters thus obtained are indicators of cardiovascular events. However, the interpretation of forward and reflected waves is still not generally agreed upon. We used...
