A method and system for conducting atrial defibrillation of a patient while mitigating the rest of the defibrillation countershock to prevent unwanted ventricular fibrillation. The system comprises an atrial sensing electrode subsystem, an atrial defibrillation subsystem, a ventricular pacing electrode subsystem, a power source subsystem to provide atrial defibrillation, a power source subsystem to provide ventricular pacing discharge, and a control subsystem to synchronize atrial defibrillation discharge with ventricular pacing so that atrial defibrillation discharge occurs during the QRS phase of a ventricular contraction cycle.
