The device for blood flow property measurement in the body and the method of its connection to the subject enables to measure electrical impedance in the main parts of body simultaneously. The impedance is spatially localized in the particular scanning channels (5) both by the placement of the current electrodes (9) of the alternating current source (2) and by setting their frequencies, and by proper spatial placement of the voltage electrodes (6). For the purpose of the whole body measurement at least three current generators (1) and twelve scanning channels (5) are used. The number of scanning channels (5) can be adjusted as necessary. By means of this device it is possible to monitor blood pulse waves or blood flow in the particular parts of human body.
