Abstract

A medical device system that receives cardiac data representing a plurality of stored arrhythmic episodes, and analyzing the cardiac data to identify and display a subset of stored arrhythmic episodes as a function of user-specified episode criteria. The medical device system presents a query window on an interactive display in order to receive user-specified episode criteria via one or more input fields. The medical device displays only those episodes matching the episode criteria such as arrhythmia type, zone of detection, date of occurrence and average heart rate in beats per minute (BPM).

Claims

1. A medical device programmer communicating with an implantable medical device, the programmer comprising:

a user input device adapted to receive user-specified episode criteria;

electronic circuitry coupled to the user input device, the electronic circuitry adapted to receive cardiac data representative of a plurality of arrhythmic episodes from the implantable medical device and analyze the cardiac data to identify a subset of the plurality of arrhythmic episodes according to the user-specified episode criteria; and

a display screen, coupled to the electronic circuitry, to display the identified subset of the plurality of arrhythmic episodes.

2. The programmer of claim 1, wherein the display screen comprises a query summary window configured to summarize the user-specified episode criteria.

3. The programmer of claim 2, wherein the display screen further comprises a query input window configured to allow a user to enter the user-specified episode criteria.

4. The programmer of claim 3, wherein the display screen is an interactive screen, and the user input device includes the interactive screen.

5. The programmer of claim 4, wherein the display screen comprises a log window adapted to display the identified subset of the plurality of arrhythmic episodes in a tabular format.

6. The programmer of claim 4, wherein the display screen is configured to display graphical depiction of the identified subset of the plurality of arrhythmic episodes.

7. A medical device programmer communicating with an implantable medical device, the programmer comprising:

electronic circuitry adapted to receive cardiac data representative of a plurality of arrhythmic episodes from the implantable medical device and analyze the cardiac data to identify a subset of the plurality of arrhythmic episodes according to user-specified episode criteria; and

an interactive screen coupled to the electronic circuitry, the interactive display screen configured to receive the user-specified episode criteria and to display the identified subset of the plurality of arrhythmic episodes.

8. The programmer of claim 7, wherein interactive screen comprises a query input window configured to receive the user-specified episode criteria.

9. The programmer of claim 8, wherein the interactive screen comprises a query summary window to summarize the user-specified episode criteria.

10. The programmer of claim 9, wherein the query input window comprises an occurrence date input configured to allow selection of the subset of the plurality of arrhythmic episodes based on a specified range of dates.

11. The programmer of claim 9, wherein the query input window comprises a type selection input configured to allow selection of the subset of the plurality of arrhythmic episodes based on an episode type.

12. The programmer of claim 9, wherein the query input window comprises a zone selection input configured to allow selection of the subset of the plurality of arrhythmic episodes based on a zone of detection.

13. The programmer of claim 9, wherein the query input window comprises a rate selector configured to allow selection of the subset of the plurality of arrhythmic episodes based on an average heart rate range.

14. The programmer of claim 9, wherein the query input window comprises a therapy selection input configured to allow selection of the subset of the plurality of arrhythmic episodes based on a therapy delivered prior to an episode of the plurality of arrhythmic episodes.

15. A method for operating a medical device programmer, the method comprising:

receiving cardiac data representative of a plurality of arrhythmic episodes from an implantable medical device;

receiving the episode criteria from a user input device;

identifying a set of arrhythmic episodes from the plurality of arrhythmic episodes according to the received episode criteria; and

displaying the identified set of arrhythmic episodes on the display screen of the medical device programmer.

16. The method of claim 15, further comprising presenting episode criteria inputs on the display screen.

17. The method of claim 16, wherein presenting the episode criteria inputs comprises presenting a plurality of user-modifiable data filters.

18. The method of claim 17, wherein displaying the identified set of arrhythmic episodes comprises displaying the identified set of arrhythmic episodes in a spread-sheet format.

19. The method of claim 17, wherein displaying the identified set of arrhythmic episodes comprises displaying a graphical depiction of the identified set of arrhythmic episodes.

20. The method of claim 17, further comprising displaying a summary of the plurality of arrhythmic episodes in a spread-sheet format.
