Abstract:
1. A process for processing signals representative of cardiac myocardium depolarization potentials, said signals being collected by a plurality of endocardial electrodes of an active implantable medical device such as an implantable pacemaker, device for resynchronization, cardioversion and/or defibrillation, the process being performed by one of: the active implantable medical device, an external programmer, data server, the process comprising the steps of: a) acquiring a plurality of endocardial electrogram signals (EGM) through a plurality of leads, each lead of the plurality of leads being collected between at least two pairs of endocardial electrodes selected from the plurality of endocardial electrodes; b) calculating, through a combination of the plurality of endocardial electrogram signals (FGM) acquired at step a), a corresponding endocardial vectogram (VGM); d) estimating, based upon the endocardial vectogram calculated at step b), a reconstructed surface vectocardiogram (VCGreconstructed); and e) reconstructing surface electrocardiogram signals (ECG) corresponding to said reconstructed surface vectocardiogram (VCGreconstructed).
