Abstract:
1. A method of providing electrical neurostimulation therapy to a patient using, at least in part, an implanted neurostimulator, said method comprising: sensing at least two physiological parameters in the body of a patient selected from the group consisting of an action potential in a cranial nerve, a heart parameter, a temperature, and a blood parameter; for each of said at least two physiological parameters, generating a first series of signals representative of the physiological parameter sensed over a first time period; storing each of said first series of signals as a time sequence data stream representative of said physiological parameter; determining when a physiological event has occurred in said patient; providing an indication of the occurrence of said physiological event; analyzing each of said time sequence data streams for a predetermined time interval preceding said event to determine at least one marker in said data streams as a predictor of said event; again sensing said at least two physiological parameters in said patient; for each of said at least two physiological parameters, generating a second series of signals representative of the physiological parameter sensed; analyzing each of said second series of signals to determine whether or not said at least one marker is present; and providing an electrical pulse from said implanted neurostimulator to a cranial nerve in the patient when said marker is present in said second series of signals.
