Pulse wave analysis and hypertension
Journal of Hypertension, 2004One hundred and thirty years ago, long before the routine use of blood pressure measurement, Mahmoud [1] advocated pulse wave analysis as a means of evaluating the functional integrity of the circulation. Enthusiasm for this approach subsequently diminished when sphygmomanometry emerged as a simple and reliable means of recording peripheral blood ...

Toe Pulse Wave Analysis in Obliterating Atherosclerosis
Angiology, 1983Photoplethysmographic measurements were carried out in 61 limbs with angiographically documented obliterating atherosclerosis (OA) and in 72 limbs without OA. The distance P was measured between the ascending and de scending limbs of the pulse wave at the border of the upper and middle thirds of the amplitude.

Pulse Wave Velocity and Pulse Wave Analysis in Experimental Animals
2012Until a few years ago, pulse wave velocity in experimental animals (mice, rats, rabbits, etc.) could only be measured by invasive methods. The carotid or femoral artery was surgically isolated and catheterized to assess intra-arterial pressure. The carotid and femoral signals were measured simultaneously, and the pulse wave transit time was then ...

Blood Pressure Monitoring, 2019
Pulse wave analysis (PWA) over the carotid artery is one of the available methodological options to obtain central arterial pressures and other important hemodynamic parameters. However, limited data exist relating the PWA estimates of one carotid artery over the contralateral one as the majority of the available data rely on measures over the right ...

Instruments for Pulse Wave Analysis and Measurement of Pulse Wave Velocity
2012Over the last few years, a lot of new instruments for pulse wave analysis or measurement of pulse wave velocity have been launched onto the market. It seems that their main aim is to supply operator-independent devices, which can perform faster, while the accuracy of the measurement or the scientific soundness of the algorithms used are of secondary ...

Analysis of the Wave Pattern of CSF Pulse Wave
1980Even though many studies have been performed to monitor continuous intracranial pressure (ICP) since Lundberg (I) reported, the pulsation of CSF has not been precisely studied in the wave pattern. This study aims at analyzing the pressure fluctuation in CSF as the wave pattern.

Analysis of intracranial pressure pulse wave in experimental hydrocephalus
Child's Nervous System, 1994Much has been written about the relationship between the pulse pressure (PP) of the intracranial pressure pulse wave (ICPPW) and ventricle dilatation. Some data suggest that high PP is the cause of ventricle dilatation, and other authors have reported that high PP results from decreased intracranial compliance.

Noise immunity of pulse wave contour analysis
Izmeritel`naya Tekhnika, 2019This article is devoted to analyzing the noise immunity of pulse waveform contour analysis. Different approaches to the implementation of the pulse waveform contour analysis were considered. It was demonstrated that a classical approach for the morphological analysis of the pulse wave based on using the stiffness index and the reflection index do not ...
