Abstract
State of cardiovascular system is possible to evaluate noninvasively thanks to analysis of pulse wave. Pulse wave is produced by heart which squirts blood to artery during systole. It is effect of changing in volume of blood vessels during propagation of blood. Pulse wave is affected by properties of blood vessel, as stiffness and diameter, and heart’s work. Thanks to shape and time properties of pulse wave it is possible to evaluate state of cardiovascular system. Measurement of pulse waves from different parts of human body could bring complex information about state of cardiovascular system in whole human body. For such a measurement it is necessary to develop precise device which will be able to measure several pulse waves simultaneously without time delay between measuring channels. Paper describes developing of such device which also includes one channel for ECG measurement as time synchronization. For precise measurement was also developed measuring software for displaying of measured signals and their analysis.
