A non-invasive diagnostic physiological monitoring system for mammals, particularly humans is disclosed. The system includes: at least two surface contact electrodes; means for holding the electrodes in contact with an exterior surface of a mammal; means for pairing the electrodes; an electroni c block coupled to at least one of the pairings wherein the block includes a transmitter for transmitting a predetermined electrical signal to a first pa ir of electrodes in the pairing, and a detector for detecting electrical impedance characteristics on the first pair of electrodes or on a second pai r of electrodes in the pairing; and a signal processor coupled to the detector wherein the electrical impedance characteristics are divided into at least t wo groups by frequency. According to the preferred embodiment the electrodes paired by the means for pairing are less than 15 cm distant from one another . Furthermore, the preferred system's electrical impedance characteristics are divided into three groups by frequency, wherein the first group is for frequency components of the characteristics of less than about 0.01 Hz, the second group is for frequency components of the characteristics of from abou t 0.01 Hz to about 0.4 Hz, and the third group is for frequency components of the characteristics of from about 0.4 Hz to about 5.0 Hz.
