Abstract
An exemplary method generates a map of a pacing parameter, a sensing parameter or one or more other parameters based in part on location information acquired using a localization system configured to locate electrodes in vivo (i.e., within a patient's body). Various examples map capture thresholds, qualification criteria for algorithms, undesirable conditions and sensing capabilities. Various other methods, devices, systems, etc., are also disclosed.
Claims10
A system comprising:
- one or more processors;
- memory;
- and
- control logic configured to:
- select an electrode configuration for delivery of cardiac pacing stimuli wherein the electrode configuration comprises at least one in vivo electrode;
- acquire location information for one or more of the at least one in vivo electrode of the selected electrode configuration;
- determine a capture threshold value responsive to delivering cardiac pacing stimuli using the selected electrode configuration;
- select another electrode configuration for delivery of cardiac pacing stimuli wherein the electrode configuration comprises at least one in vivo electrode;
- acquire location information for one or more of the at least one in vivo electrode of the selected other electrode configuration;
- determine a capture threshold value responsive to delivering cardiac pacing stimuli using the selected other electrode configuration;
- for the selected electrode configuration and the selected other electrode configuration, generate a map that maps the corresponding capture threshold values onto a diagram of cardiac anatomy based on the acquired location information for the selected electrode configuration and the acquired location information for the selected other electrode configuration;
- and
- render the map and cardiac anatomical markers to a display to present, on the diagram, a relationship between the capture threshold values and the cardiac anatomy.
