Claim One:
1. A method of processing cardiac signals, comprising: acquiring cardiac signals; generating a derivative of the acquired cardiac signals; performing morphology discrimination based on inflection points of the derivative of the acquired cardiac signals; and identifying, based on the morphology discrimination, a cardiac condition associated with at least a portion of the cardiac signals, wherein: the acquired cardiac signals comprise a baseline set of cardiac signals; and wherein; performing morphology discrimination comprises generating baseline information based on inflection points of the derivative of the baseline set of cardiac signals; the generation of the baseline information comprises processing the derivative of the baseline set of cardiac signals to generate a first set of shape vectors; the acquired cardiac signals further comprise a second set of cardiac signals; the derivative of the second set of cardiac signals are processed to generate a second set of shape vectors; and performing morphology discrimination further comprises scoring the second set of shape vectors using the baseline information.
