1. A system for acquiring and analyzing electrograms in myocardial tissue comprisinga member supporting multiple electrodes in a three dimensional, radially expanded array adapted to be in operative association with a region of heart tissue,a first processing element including a pacing module and a signal processing module coupled to the multiple electrodes to acquire a sample of a cardiac event by entrainment pacing the heart at a predetermined location while conditioning the multiple electrodes to sense paced electrograms occurring in the tissue region during entrainment pacing, anda second processing element including means for electronically comparing the sample to a template of a cardiac event of known diagnosis and generating an output based upon the comparison, whereby the output provides a diagnostic indicator based upon entrainment pacing.
