A Block diagram of the AMM algorithm. B Initialization of the SE. The fiducial points of the SE are illustrated in the left panel: ○—the onset, □—the minimum between the onset and the main peak, *—the main peak, ◇—the minimum between the main peak and the offset, □—the offset. C Mathematical morphological filtering. The feature signal represents the average of the mathematical morphology operators top-hat and bottom-hat calculated on each 200-ms IEGM epoch. AMM, adaptive mathematical morphology; IEGM, intracardiac electrogram, SE, structuring element
