Method and system to select a neurostimulation system configuration based on cardiac rhythm feedback
First Claim
1. A method to control a configuration of a neural stimulation (NS) system having an NS device coupled to an NS lead, the method comprising:
- cycling through multiple predetermined potential NS configurations of the NS system;
setting a timer associated with an amount of time for an arrhythmia related electrophysiology change to occur in response to at least one of the predetermined potential NS configurations;
after the timer expires, collecting cardiac signals from a patient that are representative of cardiac rhythms experienced by the patient, the collecting operation in connection with each of the multiple predetermined potential NS configurations for a corresponding period of time;
deriving, from the cardiac signals collected after the timer expires, characteristic values (CVs) for at least one physiologic characteristic indicative of at least one of normal and abnormal cardiac rhythms in connection with each of the corresponding multiple predetermined potential NS configurations; and
then selecting, from the multiple predetermined potential NS configurations, an NS operating configuration to be used by the NS system based on the CVs.

Abstract
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.

20. A neural stimulation (NS) system, comprising:
-
an NS device coupled to an NS lead; memory configured to save multiple predetermined potential NS configurations; a controller configured to direct the NS device to cycle through each of the multiple predetermined potential NS configurations, the controller configured to set a timer associated with an amount of time for an arrhythmia related electrophysiology change to occur in response to at least one of the predetermined potential NS configurations and to collect cardiac signals after the timer expires; inputs configured to receive the cardiac signals that are collected from a patient over a period of time during which each of the multiple predetermined 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 collected after the time expires, 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 corresponding multiple predetermined potential NS configurations; and a CV analysis module configured to analyze the multiple CVs and then select, from the multiple predetermined potential NS configurations, an NS operating configuration to be used by the NS system based on the CVs. - View Dependent Claims (21, 22, 23, 24, 25, 26, 27, 28, 29, 30, 31, 32, 33, 34, 35, 36, 37, 38)
