Estimating pulse wave velocity from the radial pressure wave using machine learning algorithms

medRxiv, 2020
The European gold standard measurement of vascular ageing, a risk factor for cardiovascular disease, is the carotid-femoral pulse wave velocity (cfPWV), which requires an experienced operator to measure pulse waves at multiple sites.

Assessment of pulse wave velocity

Artery Research, 2008
Measurement of pulse wave velocity is of increasing importance for assessment of arterial stiffness and risk evaluation. Different techniques are available, based either on pressure, distension or Doppler waveforms. Techniques not only differ by the algorithm used to identify specific part of the pulse signal, but also in the preferred way to measure ...

Determinants of pulse wave velocity in healthy people and in the presence of cardiovascular risk factors: ‘establishing normal and reference values’

European Heart Journal, 2010
Aims Carotid–femoral pulse wave velocity (PWV), a direct measure of aortic stiffness, has become increasingly important for total cardiovascular (CV) risk estimation.

Difficulties in the measurement of pulse-wave velocity [PDF]

American Heart Journal, 1958
The methods employed in the measuring of pulse-wave velocity are subject to gross error because of alinearity and frequency distortion resulting from low-resonance frequencies of instrumentation and arterial segment and extraneous tissue interference.

Possibilities of using the ultrasonic wave transmission method to estimate initial setting time of cement paste [PDF]

, 2008
In this paper, the applicability of the ultrasonic wave transmission method to estimate the initial setting time of an arbitrary cement paste is discussed. Ultrasonic pulse velocity measurements were fully automated and measured continuously.

Pulse Wave Velocity in Familial Combined Hyperlipidemia [PDF]

American Journal of Hypertension, 2007
In the present cross-sectional study we investigated whether familial combined hyperlipidemia (FCH) is associated with an increased arterial wall stiffness, and whether measures of arterial wall stiffness in FCH family members could contribute to cardiovascular risk stratification.Ninety-eight subjects with FCH and 230 unaffected relatives filled out a

Estimation of central pulse wave velocity from radial pulse wave analysis [PDF]

Computer Methods and Programs in Biomedicine, 2022
Arterial stiffness, commonly assessed by carotid-femoral pulse wave velocity (cfPWV), is an independent biomarker for cardiovascular disease. The measurement of cfPWV, however, has been considered impractical for routine clinical application. Pulse wave analysis using a single pulse wave measurement in the radial artery is a convenient alternative ...

Universal Approach to Optimal Photon Storage in Atomic Media [PDF]

, 2007
We present a universal physical picture for describing storage and retrieval of photon wave packets in a Lambda-type atomic medium. This physical picture encompasses a variety of different approaches to pulse storage ranging from adiabatic reduction of ...
