Problems of Measuring Pulse Wave Velocity

چکیده
Problems of measuring pulse wave velocity and its utilization in diagnostics have been examined for many years. Pulse wave velocity is a quantity that can be measured non-invasively, and it may bring much information about the state of circulatory system. The R-wave of electrocardiogram (ECG) is most frequently used as the reference point for measuring the pulse wave velocity but it can also be measured as the phase shift of two pulse waves on one artery. When the pulse wave velocity is brought into correlation with blood pressure, then the method used for long term blood pressure monitoring plays an important role. In many cases, the problem of the artery branching is neglected, although this phenomenon may cause additional mistakes in final results. Key-Words: Pulse Wave Velocity, Blood Pressure, Electrocardiogram, Photoplethysmogram

A Bio Signal Processing System for Pulse Wave Velocity Detection
Pulse wave velocity (PWV) is the most popular index to assessment the arterial stiffness. Currently, several non-invasive examination methods with single channel for PWV are announced. This paper proposes a non-invasive digital volume pulse (DVP) measuring system using a dual channel simultaneous measurement method try to meet the demands for home healthcare equipment which is easy to operate. ...
متن کاملIn vivo MR measurement of arterial pulse pressure in the murine aorta
Introduction: Mouse models are increasingly used to investigate functional and cardiovascular parameters. Measurements of blood flow patterns, vessel wall strain and pulse wave velocity have been used for the evaluation of the arterial function and cardiovascular risk [1]. However noninvasive methods for measuring hemodynamic parameters such as blood pressure are not yet available. In this work...
متن کاملTelomere length as an indicator of biological aging: the gender effect and relation with pulse pressure and pulse wave velocity.
Chronological age is the primary determinant of stiffness of central arteries. Increased stiffness is an independent indicator of cardiovascular risk. The aim of this study was to determine whether telomere length, a possible index of biological aging, provides a better account than chronological age for variation in arterial stiffness, evaluated by measuring pulse pressure and aortic pulse wav...

Shear and Compressional Wave Velocities along with other Petrophysical Logs, are considered as upmost important data for Hydrocarbon reservoirs characterization. Shear Wave Velocity (Vs) in Well Logging is commonly measured by some sort of Dipole Logging Tools, which are able to acquire Shear Waves as well as Compressional Waves such as Sonic Scanner, DSI (Dipole Shear Sonic imager) by Schlumbe...
متن کاملAccurate method for measuring arterial pulse wave velocity by cardiovascular magnetic resonance
A modified version of the flow-area (QA) method for measuring pulse wave velocity (PWV) from CMR images is introduced. The new ‘flow-time-area’ (QTA) method is more robust to errors in area measurements than the QA method, which is mathematically proved and demonstrated in pulmonary hypertension study. PWV was correlated to measurements from catheterization, echo, and CMR. The effect of image r...
