Pulse wave velocity in the carotid artery [PDF]

2008 IEEE Ultrasonics Symposium, 2008
The pulse wave velocity (PWV) in the carotid artery (CA) has been estimated based on ultrasound data collected by the experimental scanner RASMUS at DTU. Data is collected from one test subject using a frame rate (FR) of 4000 Hz. The influence of FRs is also investigated.

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

, 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 ...

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

BioMedical 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

Elevated levels of urine isocitrate, hydroxymethylglutarate, and formiminoglutamate are associated with arterial stiffness in Korean adults

Scientific Reports, 2021
Recent evidence suggests that cellular perturbations play an important role in the pathogenesis of cardiovascular diseases. Therefore, we analyzed the association between the levels of urinary metabolites and arterial stiffness. Our cross-sectional study

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

, 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.

The Association between Inflammation and Pulse Wave Velocity in Dyslipidemia: An Evidence-Based Review

Mediators of Inflammation, 2020
Dyslipidemia is associated with increased arterial stiffness (AS) which may lead to hypertension. Among the methods to assess AS are carotid-femoral and brachial-ankle pulse wave velocity. Dyslipidemia is also known to trigger inflammation.

Venous pulse wave velocity [PDF]

Vascular Pharmacology, 2020
Central venous pressure and volume status are relevant parameters for the characterization of the patient's haemodynamic condition and for the management of fluid therapy however, their invasive assessment is affected by various risks and complications while non-invasive approaches provide only imprecise and subjective indications.
