Pulse Wave Velocity in Postmenopausal Women [PDF]

open access: yesPulse, 2013
Cardiovascular disease (CVD) and osteoporosis are major causes of morbidity and mortality in postmenopausal women. The relationship between atherosclerosis and osteoporosis has been established by studies of the underlying pathophysiological mechanisms and biochemical pathways that seem to overlap in many places. Pulse wave velocity (PWV) is one of the

Determination of wave speed and distensibility of flexible tubes using diameter and velocity [PDF]

open access: yes, 2009
It is well accepted that wave speed is one of the key factors describing wave propagation in arteries. Local wave speed is directly related to the mechanical properties of the arterial wall and is widely used to determine the arterial distensibility ...

Automating the determination of wave speed using the pu-loop method [PDF]

open access: yes, 2005
The PU-loop (pressure-velocity loop) is a method for determining wave speed and relies on the linear relationship between the pressure and velocity in the absence of reflected waves.

Simultaneous determination of wave speed and arrival time of reflected waves using the pressure-velocity loop [PDF]

open access: yes, 2007
This is the post print version of the article. The official published version can be found at the link below.In a previous paper we demonstrated that the linear portion of the pressure–velocity loop (PU-loop) corresponding to early systole could be used ...

Frequency conversion based on three-wave parametric solitons [PDF]

open access: yes, 2010
Parametric three-wave mixing in quadratic nonlinear crystals provides a versatile means of achieving widely tunable frequency conversion of laser light, thus permitting a substantial extension of the wavelength coverage of laser sources across broad ...

Brachial-ankle pulse wave velocity and symptomatic cerebral infarction in patients with type 2 diabetes: a cross-sectional study

open access: yesCardiovascular Diabetology, 2003
Background Recently a new automatic device that measures brachial-ankle pulse wave velocity using an oscillometric method has been developed. However, the practical significance of brachial-ankle pulse wave velocity measurement remains uncertain.

Validity and reproducibility of arterial pulse wave velocity measurement using new device with oscillometric technique: A pilot study

open access: yesBioMedical Engineering OnLine, 2005
Background Availability of a range of techniques and devices allow measurement of many variables related to the stiffness of large or medium sized arteries. There is good evidence that, pulse wave velocity is a relatively simple measurement and is a good
