Claim 10:
11. A method for quantifying a fusion rate, the method comprising:
capturing, by one or more electrodes of an implantable medical device, at least two endocardial electrogram (EGM) signals during a first cardiac cycle;
deriving, from the at least two EGM signals, at least two distinct temporal components;
combining the at least two temporal components to generate a first parametric curve representative of the first cardiac cycle; and
comparing the first parametric curve with a first reference curve corresponding to a complete capture situation to generate a first value for at least one descriptive parameter;
comparing the first parametric curve with a second reference curve corresponding to a ventricular spontaneous rhythm situation to generate a second value for the at least one descriptive parameter; and
in response to an occurrence of a fusion situation, generating a metric that quantifies the fusion rate for the fusion situation based on the first value and the second value.
