Piezoelectric sensor determination of arterial pulse wave velocity

Piezoelectric sensor determination of arterial pulse wave velocity.

Arterial pulse wave velocity (APWV) is a measure of the elasticity (or stiffness) of peripheral arterial blood vessels. The pulse referred to here will be the pressure pulse as opposed to the flow pulse measured by ultrasound Doppler. The pressure pulse velocity varies over the range from about 12 m s(-1) to 15 m s(-1) in stiff peripheral arteries, whereas in normal arteries it has a velocity i...

Arterial pulse wave velocity and heart rate.

Arterial Pulse Wave Velocity and Heart Rate

To the Editor: The concerns raised by Lantelme et al1 about the relationship between heart rate and pulse wave velocity (PWV) properly apply to the method they employed, not to the conventional method, nor to the long-established relationship between PWV and arterial stiffness. Lantelme et al used Complior, as did the 3 other studies (Lantelme references 8, 15, 17), which appeared to show incre...

Accuracy of arterial pulse-wave velocity measurement using MR.

The performance of a one-dimensional MR technique for the estimation of pulse-wave velocity in the aorta was evaluated. An expression for the error in this estimate was formulated and verified both by simulation and by experiment. On the basis of this formulation, guidelines for increasing the efficiency of the acquisition were established. The technique was further validated by comparison with...

Pulse 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...
