Abstract

A dynamic graphical display for presenting patient data received from a medical device automatically sorts the patient data into a Venn diagram type format. In one embodiment, the graphical display includes two or more graphic objects representing different types of physiological parameters or events derived from the physiological parameters. The graphic objects define at least a first section corresponding to a first subset of patient data, a second section corresponding to a second subset of patient data, and a third section corresponding to a conjunction of the first and second subsets of patient data. In some embodiments, a user may select one of the sections of the graphical display to obtain further details about the respective subset of patient data or conjunction of subsets of data.

Claims

1. A method comprising:

receiving patient data from a medical device;

generating a graphical user interface comprising a plurality of graphic objects defining at least;

a first section corresponding to a first subset of patient data;

a second section corresponding to a second subset of patient data; and

a third section corresponding to a conjunction of the first and second subsets of patient data; and

presenting the graphical user interface via a display.

2. The method of claim 1, wherein at least one of the first, second or third sections are selectable by a user.

3. The method of claim 1, further comprising:

receiving user input selecting one of the first, second or third sections; and

presenting output data corresponding to a respective subset of patient data within a selected one of the first, second or third sections.

4. The method of claim 1, wherein receiving patient data from the medical device comprises receiving patient data from an implantable medical device via wireless telemetry.

5. The method of claim 1, wherein receiving patient data from a medical device comprises receiving physiological parameter measurements from the medical device, the method further comprising deriving events from the physiological parameter measurements for inclusion in at least one of the first or second subsets of patient data.

6. The method of claim 5, wherein the physiological parameter comprises at least one of:

electrocardiogram measures, electroencephalogram measures, blood pressure measurements, electrical activity of a heart of a patient, minute ventilation, cardiovascular pressure measures, venous oxygen levels, blood pressure patient activity level or body temperature.

7. The method of claim 5, wherein deriving events from the physiological parameter measurements comprises comparing at least one of the physiological parameter measurements to a threshold value.

8. The method of claim 5, wherein the physiological parameter measurements comprise measurements of a first type of physiological parameter, wherein deriving events comprises comparing a trend in the measurement of the first type of physiological parameter to a template.

9. The method of claim 8, wherein the trend indicates a rate of change of the measurement of the first type of physiological parameter over a period of time.

10. The method of claim 1, wherein the physiological parameter measurements comprise measurements of a first type of physiological parameter and a second type of physiological parameter, wherein deriving events comprises analyzing a first frequency component of a waveform of the measurement of the first type of physiological parameter and comparing the first frequency component to a second frequency component of a waveform template.

11. The method of claim 1, further comprising receiving an indication from a patient and generating a patient marker for inclusion in at least one of the first or second subsets of patient data upon receiving the indication from the patient.

12. The method of claim 1, wherein generating the graphical user interface comprises:

determining whether a first data record within the first subset of patient data and a second data record within the second subset of patient data occurred within a predetermined range of time; and

associating the first and second data records within the third section if the first and second data records occurred within the predetermined range of time.

13. The method of claim 12, wherein the predetermined time range is less than one minute.

14. The method of claim 1, wherein generating the graphical user interface comprises:

determining whether a first data record within the first subset of patient data and a second data record within the second subset of patient data occurred in a predetermined order; and

associating the first and second data records in with the third section if the first and second data records occurred in the predetermined order.

15. The method of claim 1, wherein the plurality of graphic objects define a Venn diagram.

16. A system comprising:

a display;

a user interface;

a telemetry module configured to receive patient data from a medical device; and

a processor configured to;

generate a graphical user interface comprising a plurality of graphic objects defining at least;

a first section corresponding to a first subset of patient data;

a second section corresponding to a second subset of patient data; and

a third section corresponding to a conjunction of the first and second subsets of patient data; and

display the graphical user interface on the display.

17. The system of claim 16, wherein at least one of the first, second or third sections is selectable by a user, and wherein the processor is further configured to:

receive user input selecting one of the first, second or third selectable sections; and

display a respective subset of patient data corresponding to the selected one of the first, second or third selectable sections.

18. The system of claim 16, wherein the processor is further configured to derive events from raw physiological parameter measurements.

19. The system of claim 18, wherein the processor derives the events by comparing at least one of the physiological parameter measurements to a threshold value.

20. The system of claim 18, wherein the physiological parameter measurements comprise measurements of a first type of physiological parameter and a second type of physiological parameter, wherein the processor derives the events by comparing a trend in the measurement of the first type of physiological parameter to a template.

21. The system of claim 18, wherein the physiological parameter measurements comprise measurements of a first type of physiological parameter and a second type of physiological parameter, wherein the processor derives the events by analyzing a first frequency component of a waveform of the measurement of the first type of physiological parameter and comparing the first frequency component to a second frequency component of a waveform template.

22. The system of claim 16, wherein at least one of the first or second subsets of patient data comprises patient markers.

23. The system of claim 16, wherein the conjunction of the first and second subsets of patient data comprises data records within the first and second subsets that occurred within a predetermined range of time as each other.

24. A graphical display comprising:
