Reproducibility of Regional Pulse Wave Velocity in Healthy Subjects
BACKGROUND/AIMS Despite the clinical importance and widespread use of pulse wave velocity (PWV), there are no standards for pulse sensors or for system requirements to ensure accurate pulse wave measurement. We assessed the reproducibility of PWV values using a newly developed PWV measurement system. METHODS The system used in this study was the PP-1000, which simultaneously provides regional...
متن کاملestimation of carotid artery pulse wave velocity by doppler ultrasonography
background: pulse wave velocity (pwv) is widely used for estimating the stiffness of an artery. v arious invasive and non-invasive methods have been developed to determine pwv over the years. in the present research , the non-invasive estimation of the pwv of large arteries was used as an index for arterial stiffness. methods: a dynamic model based on the navier-stokes equations coupled to elas...
متن کاملPulse Wave Analysis and Pulse Wave Velocity
momanometer that provides arterial pressures (brachial systolic and diastolic pressure) is coming under question. The concerns extend well beyond the familiar issue of “white coat” hypertension, home and 24-h blood pressure recordings, and the phase-out of mercury based instruments. These concerns relate to the inaccuracy of all cuff devices for measuring pressure within the brachial artery, th...
متن کاملOptimized Estimation of Global and Regional Aortic Pulse Wave Velocity
Introduction: Pulse wave velocity (PWV) as a measure of aortic stiffness is an important clinical marker for the presence of atherosclerosis [1,2]. For PWV estimation using Phase contrast (PC) MRI transit-time (TT) methods have been employed which estimate temporal differences in flow waveforms between two locations in the vessel with known distance [3]. However, precision was limited by the ac...
متن کاملNoninvasive Method for Measuring Local Pulse Wave Velocity by Dual Pulse Wave Doppler: In Vitro and In Vivo Studies
OBJECTIVES To evaluate the validity and reproducibility of a noninvasive dual pulse wave Doppler (DPWD) method, which involves simultaneous recording of flow velocity of two independent sample volumes with a measurable distance, for measuring the local arterial pulse wave velocity (PWV) through in vitro and in vivo studies. METHODS The DPWD mode of Hitachi HI Vision Preirus ultrasound system ...
