The present disclosure provides neurostimulation systems and methods. A neurostimulation system includes at least one anode, at least one cathode, the at least one anode and the at least one cathode configured to apply electrical stimulation to a patient, and a controller electrically coupled to the at least one anode and the at least one cathode, the controller configured to determine when one of the at least one anode and the at least one cathode fails, measure, in response to the determination, a quantity indicative of a charge density of the applied electrical stimulation, compare the measured quantity to a predetermined limit, and perform at least one action when the measured quantity exceeds the predetermined limit.

Systems and methods for monitoring charge density of electrical stimulation

Methods and systems are provided to control a configuration of a neural stimulation (NS) system having an NS device coupled to an NS lead. The methods and systems change between configurations of the NS system and collect cardiac signals from a patient that are representative of cardiac rhythms experienced by the patient over a period of time and in connection with multiple NS configurations. The methods and systems derive, from the cardiac signals, characteristic values for at least one physiologic characteristic indicative of at least one of normal and abnormal cardiac rhythms in connection with the multiple NS configurations; and select, from the multiple NS configurations, an NS operating configuration to be used by the NS system based on the characteristic values.

Method and system to select a neurostimulation system configuration based on cardiac rhythm feedback

Stimulation of a patient's nervous system is controlled based on cardiovascular risk assessment performed by an implantable medical device. For example, an implantable medical device may monitor cardiac electrical activity to detect changes in the ST segment. Upon detection of a certain change in the ST segment, the implantable medical device controls the application of spinal cord stimulation and/or other neurostimulation to cardiac-related sections of the patient's nervous system. In some embodiments, the implantable medical device communicates with a separate neurostimulation device to control the neurostimulation. In some embodiments, the implantable medical device delivers the neurostimulation.
