Abstract:
1. A method of generating a template in an implantable medical device, comprising: sensing a plurality of events; determining whether there are first consecutive events of the plurality of events having first characteristics; waiting until there are first consecutive events of the plurality of events having first characteristics; identifying, in response to the first consecutive events of the plurality of events having first characteristics, a predetermined number of events of the plurality of events subsequent to the first consecutive events having second characteristics as first selected events; generating the template from only the first selected events; generating a plurality of cross-matches between the predetermined number of events, the generating the plurality of cross-matches comprising matching a first event of the predetermined number of events to a second event of the predetermined number of events to compute a cross-match between the first event of the predetermined number of events and the second event of the predetermined number of events; and determining whether a predetermined number of the plurality of generated cross-matches are within a predetermined cross-match threshold, wherein the template is generated from events of the predetermined number of events corresponding to the cross-matches determined to be within the cross-match threshold.
