The reconstruction of a surface electrocardiogram based upon an endocardial electrogram. This method includes: (a) acquisition ( 10 ) of a plurality of endocardial electrogram signals (EGM) through a plurality of endocardial derivations defined based upon endocardial electrodes; (b) calculation ( 12 ), by combining the endocardial electrogram (EGM) signals acquired at step (a), of the corresponding endocardial vectogram (VGM); (c) angular resealing ( 14 ) of the orthonormated mark of the endocardial vectogram (VGM) with that of the surface vectocardiogram (VCG); (d) estimation ( 16 ), based upon the endocardial vectogram (VGM) calculated at step (b), of a reconstructed surface vectocardiogram (VCG<SUB>reconstructed</SUB>), and (e) calculation ( 18 ) of the surface electrocardiogram (ECG) corresponding to said reconstructed surface vectocardiogram (VCG<SUB>reconstructed</SUB>).
