Abstract

La présente invention concerne un procédé et un système de défibrillation permettant de traiter un coeur présentant une arythmie ventriculaire, par prétraitement d'une zone de tissu cardiaque entourant une électrode de défibrillation à l'aide de plusieurs impulsions de stimulation cardiaque à haute énergie. Les multiples impulsions électriques à haute énergie sont appliquées à la zone de tissu cardiaque entourant la première électrode de défibrillation pour prévenir des contractions ventriculaires aberrantes du coeur pendant un intervalle de repos suivant l'administration du choc de défibrillation, ce qui permet d'accroître la probabilité de rétablissement du coeur sujet à une fibrillation. Les multiples impulsions électriques peuvent également être appliquées à la zone de tissu cardiaque entourant l'électrode de défibrillation pour influencer l'état de signaux complexes de fibrillation ventriculaire à gros grains, ces multiples impulsions électriques de stimulation cardiaque permettant de produire ou d'accroître des signaux complexes de fibrillation ventriculaire à gros grains. Les signaux complexes de fibrillation ventriculaire à gros grains peuvent ensuite être utilisés pour coordonner l'administration d'un nouveau choc de défibrillation.
