Methods and systems for automatically identifying detection parameters for an implantable medical device

摘要

An initial set of parameters for operating one or more detection tools is automatically derived and subsequently adjusted so that each detection tool is more or less sensitive to signal characteristics in a region of interest. Detection tool(s) may be applied to physiological signals sensed from a patient (such as EEG signals) and may be configured to run in an implanted medical device that is programmable with the parameters to look for rhythmic activity, spiking, and power changes in the sensed signals, etc. A detection tool may be selected and parameter values derived in a logical sequence and/or in pairs based on a graphical representation of an activity type which may be selected by a user, for example, by clicking and dragging on the graphic via a GUI. Displayed simulations allow a user to assess what will be detected with a derived parameter set and then to adjust the sensitivity of the set or start over as desired.

1. A method for automatically deriving, through a computer, a parameter set for a detection tool implemented in an active medical device implantable in a patient for detecting electrographic activity, the method comprising:
receiving through a user interface coupled to the computer, an indication of at least one region of interest in a portion of a signal, the at least one region of interest having at least a starting point; analyzing the at least one region of interest via an activity type algorithm resident in the computer, to determine from among a plurality of different activity types, a determined activity type with which to characterize the at least one region of interest; automatically selecting, via an algorithm resident in the computer, a type of a detection tool based on the determined activity type; further analyzing the at least one region of interest via an algorithm resident in the computer, to automatically derive a set of operating parameters for the selected type of detection tool, the set of automatically-derived operating parameters and the selected type of detection tool defining an instance of a detection tool; and displaying a simulation through the user interface, the simulation corresponding to the electrographic activity the instance of the detection tool is likely to detect.
