Abstract
Disclosed are systems, devices and methods that produce at least two distinct temporal components from two distinct endocardial electrogram (EGM) signals collected concurrently, determines a non-temporal 2D characteristic representative of the cardiac cycle to be analyzed, from the variations of one of the temporal components as a function of another of the temporal components and comparing the characteristic of the current cycle to two reference characteristics previously obtained and stored, one in a situation of complete capture and the other in a situation of spontaneous rhythm. Respective values of similarity descriptors are derived of these two comparisons, which are used to calculate a metric quantifying a fusion rate.
