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 display screen of a medical device programmer for communicating with an implantable cardiac defibrillator, comprising:

a query summary window configured to summarize user-specified episode criteria; and

a log window configured to present a subset of arrhythmic episodes including episode data in a tabular format according to the user-specified episode criteria, the subset of arrhythmic episodes identified from cardiac data representative of a plurality of arrhythmic episodes using the user-specified episode criteria, the episode data indicating a number of antitachycardia pacing therapies and a number of shock therapies associated with each arrhythmic episode of the subset of arrhythmic episodes, the cardiac data received from the implantable cardiac defibrillator and including the episode data.

2. The display screen of claim 1, comprising a query input window configured to receive the user-specified episode criteria.

3. The display screen of claim 2, wherein the query input window comprises an occurrence date input field to receive a range of dates of occurrence.

4. The display screen of claim 2, wherein the query input window comprises a type selection input field to receive one or more episode types.

5. The display screen of claim 2, wherein the query input window comprises a zone selection input field to receive a zone of detection associated with detection criteria.

6. The display screen of claim 2, wherein the query input window comprises a rate selector input field to receive a detection range specified by average heart rates during each arrhythmic episode of the plurality of arrhythmic episodes.

7. The display screen of claim 2, wherein the query input window comprises a therapy selection input field to receive a parameter representing a therapy delivered prior to each arrhythmic episode of the plurality of arrhythmic episodes.

8. The display screen of claim 1, wherein the log window is configured to display the subset of arrhythmic episodes in a spreadsheet format.

9. The display screen of claim 8, wherein the log window is configured to display the subset of arrhythmic episodes in a tabular format in which each row corresponds an arrhythmia episode of the subset of arrhythmic episodes.

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

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

displaying a query summary window on an interactive screen of the medical device programmer, the query summary window summarizing user-specified episode criteria;

identifying a subset of arrhythmia episodes from the cardiac data using the user-specified episode criteria; and

displaying a log window on the interactive screen, the log window presenting the subset of arrhythmic episodes including episode data of the cardiac data in a tabular format according to the user-specified episode criteria, the episode data indicating a number of antitachycardia pacing therapies and a number of shock therapies associated with each arrhythmic episode of the subset of arrhythmic episodes.

11. The method of claim 10, comprising displaying a query input window including a plurality of input fields to receive the user-specified episode criteria.

12. The method of claim 11, wherein displaying the query input window comprises displaying an occurrence date input field to receive a range of dates of occurrence.

13. The method of claim 11, wherein displaying the query input window comprises displaying a type selection input field to receive one or more episode types.

14. The method of claim 11, wherein displaying the query input window comprises displaying a zone selection input field to receive a zone of detection associated with detection criteria.

15. The method of claim 11, wherein displaying the query input window comprises displaying a detection range specified by average heart rates during each arrhythmic episode of the plurality of arrhythmic episodes.

16. The method of claim 11, wherein displaying the query input window comprises displaying a therapy selection input field to receive a parameter representing a therapy delivered prior to each arrhythmic episode of the plurality of arrhythmic episodes.

17. The method of claim 11, comprising receiving the cardiac data from an implantable medical device.

18. The method of claim 17, wherein displaying the log window comprises displaying the subset of arrhythmic episodes in a spreadsheet format.

19. The method of claim 18, wherein displaying the subset of arrhythmic episodes in the spreadsheet format comprises displayed the subset of the plurality of arrhythmic episodes in a tabular format in which each row corresponds an arrhythmia episode of the subset of arrhythmic episodes.

20. The method of claim 17, comprising displaying a graphical depiction of the subset of the plurality of arrhythmic episodes.
