Pulse Wave Velocity in Kawasaki Disease

Angiology, 2016
Kawasaki disease (KD) is an acute childhood febrile disease of unknown etiology. It exhibits not only coronary artery aneurysms in some cases but also systemic vasculitis. Whether KD is associated with accelerated atherosclerosis remains debatable. The measurement of pulse wave velocity (PWV) is useful as a simple, noninvasive measurement of arterial ...

Pulse wave velocity for cardiovascular characterization [PDF]

Proceedings of the IEEE 23rd Northeast Bioengineering Conference, 2002
Pulse wave velocity (PWV) provides a robust metric for cardiovascular health that can readily be measured non-intrusively. This paper describes efforts to develop a methodology for rapid, portable, cost effective measurement of pulse wave velocity utilizing only an electrocardiogram (EGG), continuous wave (CW) Doppler, and a computer based data ...

Wave Travel and Pulse Wave Velocity

2018
Waves generated by the heart travel down the aorta and major conduit arteries. These waves are pressure waves, flow or velocity waves or diameter waves. The ratio of the distance Δx, and the time it takes for the foot of the wave to travel over this distance, Δt, gives the wave speed or pulse wave velocity, PWV=Δx/Δt.

Carotid–femoral pulse wave velocity in the elderly

Journal of Hypertension, 2014
Predictive value of arterial stiffness in cardiovascular disease has been recognized for many decades. Carotid-femoral pulse wave velocity (cfPWV), as a noninvasive measurement, has been recommended as a gold standard of arterial stiffness, and we believe that this surrogate of arterial stiffness has been refined to the point that its utility in ...

Central pulse wave velocity is responsible for increased brachial‐ankle pulse wave velocity in subclinical hypothyroidism

Clinical Endocrinology, 2007
SummaryObjective  Subclinical hypothyroidism affects 5–15% of the general population, and is associated with increased morbidity from cardiovascular disease. We recently reported a significant increase in brachial‐ankle pulse wave velocity (baPWV), a parameter of arterial stiffening and an independent predictor for the presence of cardiovascular ...

Arterial pulse wave velocity in coronary arteries

2006 International Conference of the IEEE Engineering in Medicine and Biology Society, 2006
Pulse wave velocity is related to arterial stiffness. Pulse wave velocity changes with age and disease and is a useful indicator of cardiovascular disease. Different methods are used for evaluating pulse wave velocity in systemic vessels, but none is applicable to coronary arteries.

Investigation of pulse wave velocity in arteries

2012 35th International Conference on Telecommunications and Signal Processing (TSP), 2012
The article deals with the investigation of pulse wave propagation in arteries. A part of work involves also design and realization of devices serving for scanning of pulse wave by reflective photoplethysmography. Microcontroller with integrated A/D converter is used for conversion from analog to digital signal.

Inductive Plethysmography for aortic Pulse Wave Velocity

2020 42nd Annual International Conference of the IEEE Engineering in Medicine & Biology Society (EMBC), 2020
Aortic stiffening is a process that is linked to cardiovascular risk factor increase. Then, aortic stiffness evaluation is considered as a good index of the evolution of pathophysiological situations, including myocardial infarction, heart failure, atherosclerosis or stroke.

Pulse wave velocity and hypertension

1987
Of the many factors implicated in the genesis and maintenance of elevated arterial pressure, the pulsatile function of the arterial system has received little attention in comparison to other cardiovascular related phenomena such as increase in peripheral resistance, regulation of cardiac output, the role of the autonomic nervous system, glomerular ...

Pulse Wave Velocity Techniques

2019
Recently, pulse wave velocity (PWV), or its reciprocal pulse transit time (PTT), has been intensively investigated as a promising technique for continuous, cuffless, and noninvasive blood pressure (BP) monitoring. BP is mathematically derived through PTT, or the “time delay” in propagation of pressure waves in the vascular system, which can be easily ...
