Claim One:
1. A system for classifying tachyarrhythmias, the system comprising: a correlation input to receive a plurality of feature correlation coefficient (Fcc) values each indicative of whether an arrhythmic heart beat of a tachyarrhythmia is morphologically correlated to a template heart beat of a known type cardiac rhythm; a majority voting circuit coupled to the correlation input, the majority voting circuit adapted to classify the tachyarrhythmia as a first type tachyarrhythmia if a number of the arrhythmic heart beats that are correlated to the template heart beat equals or exceeds a predetermined threshold number; and a morphology stability analysis circuit coupled to the majority voting circuit, the morphology stability analysis circuit adapted to further classify the tachyarrhythmia based a stability associated with the Fcc values if the number of the arrhythmic heart beats that are correlated to the template heart beat is smaller than the predetermined threshold number.
