Claim Text:
1. An implantable cardiac stimulus device (ICSD) comprising a canister housing operational circuitry configured for coupling to a lead electrode assembly which has a plurality of electrodes disposed thereon such that the operational circuitry can be electrically coupled to the electrodes on the lead electrode assembly, the operational circuitry being configured to perform a method of cardiac signal analysis comprising: detecting a series of events; measuring widths of the detected events; comparing a detected event, N, to a plurality of preceding detected events to yield a set of correlations; identifying a pattern of high-low correlation among the set of correlations; assessing the width of the detected events in connection with the step of identifying a pattern of high-low correlation; and if a high-low pattern is found along with a width sequence suggesting double detection, identifying at least one of the series of detected events as an overdetection.
