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.

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.

Aortic Pulse Wave Velocity and Carotid-Femoral Pulse Wave Velocity: Similarities and Discrepancies [PDF]
Hypertension Research, 2007 The objectives of this study were to determine the relationship between carotid-femoral (cfPWV) and aortic pulse wave velocity (aPWV) and to compare their modulators and association with coronary artery disease (CAD). We studied 107 consecutive patients (68 men) with a mean age of 60.49+/-8.31 years who had stable angina and had been referred for ...

Hemodialysis Parameters and Pulse Wave Velocity
International Journal of Applied & Basic Medical Research, 2022 Abstract Aim: The study aimed to evaluate the acute effect of ultrafiltration on the mechanical properties of the aorta using brachial-ankle pulse wave velocity (PWV) before and after hemodialysis (HD). Patients and Methods: This study included 80 patients who were on a ...

Parametric Frequency Conversion of Short Optical Pulses Controlled by a CW Background [PDF]
, 2007 We predict that parametric sum-frequency generation of an ultra-short pulse may result from the mixing of an ultra-short optical pulse with a quasi-continuous wave control.

Pulse Wave Velocity in Postmenopausal Women [PDF]
Pulse, 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

Superluminal optical pulse propagation in nonlinear coherent media [PDF]
, 2002 The propagation of light-pulse with negative group-velocity in a nonlinear medium is studied theoretically. We show that the necessary conditions for these effects to be observable are realized in a three-level $\Lambda$-system interacting with a ...
