Abstract

V originále

The aim of this study is to show the usability of volume pulse wave measurement on superficial arteries, using a method as close as possible to manual palpation. The parameters evaluated can be generally assessed from the time domain, derivations, velocity, or frequency domain. In the time domain, a number of wave proportions can be measured. In this study, the parameters were derived from time and amplitude measurement of the pulse wave run. The mean coefficients of variation in (%) of parameters in one pulse waveform were: crest time 11.8; systolic amplitude 8.45; relative crest time 11.38; interwave distance 12.97; relative dicrotic amplitude 23.1; relative dicrotic time 7.15; augmentation index 13.23; PWV 6.76. The mean coefficients of variation in (%) of parameters in the long-term measurement were: crest time 9.17; systolic amplitude 10.79; relative crest time 6.91; interwave distance 3.77; relative dicrotic amplitude 11.37; relative dicrotic time 1.87; augmentation index 4.58; PWV 5.87. The variations measured are very large. As a result, it is not possible to accurately and quantitatively evaluate the pulse wave measured by palpation. The results show that the coefficients of variation for the parameters of the volume pulse wave biosignal can increase up to double-digit values.
