System for characterizing patient tissue impedance for monitoring and treatment
First Claim
1. A system for determining anatomical tissue impedance characteristics for use in medical patient monitoring and treatment decision making, comprising:
- at least one repository configured to storing 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;
a substantially passive impedance measurement network operating exclusive of active current injection;
an impedance measurement processor using said impedance measurement network and configured to automatically,receiving signal data representing a plurality of measured impedance values taken at a plurality of particular different sites of an anatomical organ anddetermining whether the received plurality of measured impedance values are within a corresponding plurality of predetermined expected impedance value ranges derived from data in said at least one repository and are correlated with an anatomical abnormality; and
an output processor configured to automatically communicating data comprising at least one message to a destination, said at least one message includes data indicating whether said received plurality of measured impedance values are within said corresponding plurality of predetermined expected impedance value ranges and indicate said abnormality.

Abstract
A system provides early prediction of heart tissue malfunction and electrophysiological pathology by determining anatomical tissue impedance characteristics for use in medical patient monitoring and treatment decision making. At least one repository of data indicates multiple predetermined expected impedance value ranges for corresponding multiple impedance measurements taken at multiple particular different sites of at least one anatomical organ. An impedance measurement processor automatically determines whether multiple measured impedance values taken at multiple particular different sites of an anatomical organ using an invasive catheter are within corresponding multiple predetermined expected impedance value ranges derived from the at least one repository. An output processor automatically communicates data comprising at least one message to a destination. The at least one message includes data indicating whether the multiple measured impedance values taken at the multiple particular different sites of the anatomical organ are within the corresponding multiple predetermined expected impedance value ranges.
