1. A method of discriminating cardiac depolarizations, comprising:
- detecting indications of a plurality of indications associated with determining the presence of a first event, the plurality of indications occurring at a rate corresponding to the first event;
storing, prior to detecting all of the plurality of indications, a plurality of segments corresponding to signals associated with the detected indications occurring at a rate corresponding to the first event;
comparing the plurality of segments; and
generating, in response to the comparing, a template for distinguishing the first event from a second event different from the first event and corresponding to the rate corresponding to the first event.

Abstract
An implantable medical device and associated method for automatically generating morphology templates during fast cardiac rhythms, confirming a provisional template as a confirmed template, and using the confirmed template to classify subsequent detected arrhythmias. A provisional SVT template may be created during a fast ventricular rate and activated as a confirmed SVT template upon verification that the fast rate was due to an SVT. The confirmed SVT template may be used to discriminate SVT from VT/VF.
