    摘要: Systems and methods for acquiring and analyzing electrograms in myocardial tissue are disclosed and described. One such method includes deploying a three dimensional, radially expanded array of multiple electrodes in operative association with a region of heart tissue; acquiring a sample of a cardiac event by placing the heart at a predetermined location using the multiple electrodes, while conditioning the multiple electrodes to sense paced electrograms occurring in the tissue region during pacing; and 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 pacing.
