1. A system for determining anatomical tissue impedance characteristics for use in medical patient monitoring and treatment decision making, comprising:

  • at least one repository of data indicating a plurality of predetermined expected impedance value ranges for a corresponding plurality of impedance measurements taken at a plurality of particular different sites of at least one anatomical organ;

    an impedance measurement processor for automatically determining whether a plurality of measured impedance values taken at a plurality of particular different sites of an anatomical organ using an invasive catheter are within a corresponding plurality of predetermined expected impedance value ranges derived from data in said at least one repository; and

    an output processor for automatically communicating data comprising at least one message to a destination, said at least one message includes data indicating whether said plurality of measured impedance values taken at said plurality of particular different sites of said anatomical organ are within said corresponding plurality of predetermined expected impedance value ranges.
