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

A neural stimulation (NS) system, comprising:

• an NS device coupled to an NS lead;
• memory configured to save multiple potential NS configurations;
• a controller configured to direct the NS device to operate cycle through each of the multiple potential NS configurations;
• inputs configured to receive cardiac signals that are collected from a patient over a period of time during which each of the multiple potential NS configurations is utilized, the cardiac signals being representative of cardiac rhythms experienced by the patient;
• a cardiac signal analysis (CSA) module configured to derive, from the cardiac signals, characteristic values (CVs) for at least one physiologic characteristic indicative of at least one of normal and abnormal cardiac rhythms that occur while the NS device operates in each of the multiple potential NS configurations;
• and
• a CV analysis module configured to analyze the CVs and select, from the multiple potential NS configurations, an NS operating configuration to be used by the NS system based on the characteristic values.
