Abstract
A method and system for automatic or semi-automatic defibrillation using redundant processing is provided. In a preferred embodiment, two microprocessors each separately analyze electrocardiogram signals from a patient in order to separately determine whether the patient should be treated. If both microprocessors determine that the patient should be treated, a treatment subsystem defibrillates the patient by delivering a defibrillation charge to the patient. In a semi-automatic embodiment, the treatment subsystem only delivers a defibrillation charge to the patient if a human operator has responded to a visual indication that the patient should be treated by manually activating the defibrillator.
