Patent ID: 6939309

Claim:
A system for displaying electrophysiology data collected from a chamber in the patient's heart, to a user, said heart having intrinsic electrical activity, said system comprising: a) a set of passive electrodes adapted for placement into position within said heart; b) a set of active electrodes adapted for placement into position within said heart; c) a pulse generator coupled to said set of active electrodes for creating and applying an electric field within said heart; d) a signal digitizer coupled to said set of passive electrodes for generating a numerical representation of electric field strength at each of said set of passive electrodes, generating a set of measured potentials; e) a signal conditioner for extracting from said measured potentials a map representation of the interior surface of said heart, and for extracting from said measured potentials a representation of said intrinsic electrical activity of said heart chamber; f) display means for displaying said representation of said electrical activity on said map representation.
