Each time your heart beats, it induces a wave along the aorta and the arterial tree. This wave leads to blood-volume changes in the vessels that expand and contract in response to these changes. Pulse wave velocity is the propagation speed of this wave along the arteries. This measurement ...
Lighthill have been computed and compared to the result computed on the 19-tube model of aorta derived from the 55-tube model of hyman systemic arterial tree by Westerhof. Variations in the local wave speed along the aorta have been computed on the model and compared to the continuous ...
An apparatus (12) for obtaining a pulse-wave-propagation-relating information of a living subject, including a bifurcate-portion determining device (20, 62, 64) which determines a bifurcate portion (22D) of an artery (22) of the subject that is present under a skin of the subject, a ...
Pulse Wave Propagation in the Arterial Tree The beating heart creates blood pressure and flow pulsations that propagate as waves through the arterial tree that are reflected at transitions in arteria... FNVD Vosse,N Stergiopulos - 《Annual Review of Fluid Mechanics》 被引量: 269发表: 2011年 ...
2.8Pulse wave velocity Thepulse wave velocity(PWV) is the speed at which the forward pressure wave is transmitted through the vascular tree[66,67]. PWV is calculated by measuring the time taken for the arterial waveform to pass between two points of a measured distance apart, and involves tak...

Any bifurcation in the arterial tree in which imped- ance match is not maintained by autonomic processes, perhaps as a result of atheroma development or a result of other vascular or neurovascular diseases, will impact wave flow downstream of such bifurcation mismatch, flow into the distal ...
Previous physics-based analyses of arterial morphology in relation to pulsatile pressure and flow, with pulse wave reflection, focused on the large arteries and required assumptions about the relative thicknesses of arterial walls and the velocities of p
Pulse Wave Imaging (PWI) is an ultrasound-based method for both qualitative visualization of the pulse wave propagation and quantitative estimation of arterial stiffness. The objective of this study is to assess the PWI performance in PWV estima- tion by comparing local abdominal aortic PWV values ...
