Abstract:
A non-invasive diagnostic physiological monitoring system for mammals, and adapted for humans, comprising:(a) one pair of surface contact electrodes; (b) an application member for holding said electrodes in contact with an exterior surface of a mammal, wherein said electrodes are embedded therein; (c) means for pairing said electrodes; (d) an electronic block coupled to said pair of electrodes wherein said block includes a transmitter for transmitting a predetermined electrical signal to said pair of electrodes, and a detector for detecting electrical impedance characteristics on said pair of electrodes; and (e) a signal processor coupled to the detector; whereinsaid electrical impedance characteristics are divided into at least two groups by frequency, and a first one of the groups is for frequency components of the characteristics of less than about 0.01 Hz.
