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 during VF to detect coarse VF complexes. The defibrillation shock is delivered in coordination with the occurrence of coarse VF complexes, and specifically to occur on the upslope portion thereof, for optimal probability of success. Preferably, DF shock is delivered on the nth occurring coarse VF complex, wherein n is equal to or greater than 2 and less than or equal to about 9.
