Abstract
Abstract: Clinicians would benefit from the evaluation of the state of the cardiovascular system, because it is one of the most important system in human body, without using invasive entrance. Multichannel pulse wave measurement could be one possibility of how to noninvasively evaluate the state of cardiovascular system. Pulse wave's properties are affected by the properties of blood vessels, like stiffness and diameter, and also by heart function. An analysis of shape and time properties of pulse wave propagation provides information about the state of the cardiovascular system. The measurement of pulse wave on different locations of human body could bring information about the different subparts of the cardiovascular system. For this kind of purpose it is necessary to developed measurement system which can achieve pulse wave measurement on several locations of the human body simultaneously and synchronously. The paper introduces developing of such system which is able to measure and displayed several PPG signals and also include one ECG channel as a time reference for synchronization. Hardware and software materials developed for the solution are described and preliminary results are presented.
