Abstract

This invention relates to an apparatus and a method for optimizing cardiac stimulation instants of a patient, wherein a signal processing chain and a set of transformations are applied to provide robust, denoised and coherent electrogram (EGM) cycles. An orthogonal (uncorrelated) transformation of observed EGMs provides an improved combination of available EGMs in terms of information content, maximizes sensitivity to changes in cardiac therapy configurations and is invariant to anatomy and lead positions of each patient. Furthermore, an original feature extraction is applied after orthogonal transformation of the EGMs and allows for calculation of a set of markers that can be better interpreted and used for optimizing the stimulation instants for a given patient.
