A method and system for ventricular defibrillation by coordinating the delivery of defibrillation shocks with sensed ventricular fibrillation complexes in a way which improves the probability of success of the defibrillation shock. Ventricular electrical activity is monitored in two ventricular locations during ventricular fibrillation to detect coarse ventricular fibrillation complexes and contractions of the ventricular cardiac tissue. The defibrillation shock is delivered in coordination with the occurrence of coarse ventricular fibrillation complexes and the contractions of ventricular cardiac tissue, and specifically to occur on the up-slope portion thereof, for optimal probability of success.

Procédé et système de défibrillation ventriculaire. Ledit procédé consiste à coordonner l'administration de chocs de défibrillation avec des complexes de fibrillation ventriculaires détectés d'une manière qui améliore la probabilité de succès du choc de défibrillation. L'activité électrique ventriculaire est surveillée sur deux sites ventriculaires pendant la fibrillation ventriculaire pour détecter les complexes de fibrillation ventriculaire à gros grains et les contractions des tissus cardiaques ventriculaires. Le choc de défibrillation est administré en coordination avec la manifestation de complexes de fibrillation ventriculaire à gros grains et de contractions des tissus cardiaques ventriculaires, et spécifiquement de manière à se produire sur la partie ascendante du tracé dudit complexe, pour une probabilité de succès optimale.
