Claim One:
1. A method involving: an implantable medical device adapted to define a plurality of sensing vectors between electrodes implanted in a patient, and a programmer adapted for communication with the implantable medical device; the method comprising: the implantable medical device capturing cardiac signal data using at least one of the plurality of sensing vectors; (x) analyzing data related to the captured cardiac signal data and: (i) determining the data indicates a plurality of likely cardiac events in relatively clear fashion and, if so, generating a score related to the at least one sensing vector by the use of a polynomial function; or (ii) determining that the data fails to indicate a plurality of likely cardiac events in relatively clear fashion; and (y) if a score is generated in step (x), comparing the score to a threshold and, (i) if the threshold is at least met, determining that an identified sensing vector is suitable for cardiac event detection; or (ii) if the threshold is not met, determining that one or more other sensing vectors is to be analyzed.
