Abstract

A system and method for correlating health related data for display. The system includes a medical device recording data and a display producing device which correlates the data and simultaneously displays different types of data or displays two sets of the same type of data along with the circumstances at which the two sets of data were recorded. Such displays aid a physician in prescribing and ascertaining the efficacy of cardiac therapies.

Claims

1. A cardiac rhythm management system comprising a cardiac rhythm management (CRM) device and a data correlation device,

said CRM device including programmable parameters controlling operation of said CRM device;

said data correlation device being adapted to receive data from said cardiac rhythm management device, said data correlation device including a memory, a processor and an output unit for displaying data, said memory storing a first data set and a second data set, said first data set being a type distinct from said second data set, said second data set including a type and a time of setting the programmable parameter, said processor correlating said first data set and said second data set and sending said correlated first and second data sets to said output unit, said first and second data sets being simultaneously displayed by said output unit.

2. The system according to claim 1, wherein said first data set is periodically collected data and said second data set is asynchronous data.

3. The system according to claim 1, wherein said at least one CRM device parameter includes an accelerometer response factor, said first data set is patient activity data, and said second data set includes the time at which said accelerometer response factor was changed.

4. The system according to claim 1, wherein said at least one CRM device parameter includes ventricular sensitivity, said first data set is the number of shocks in a given time period, and said second data set includes the time at which said ventricular sensitivity was changed.

5. The system according to claim 1, wherein said first data set includes patient health data, said second data set including a type and a time of therapy administered by said cardiac rhythm management system.

6. The system according to claim 5, wherein said first data set includes patient activity data and pacing chamber data.

7. The system according to claim 1, wherein said data correlation device is a programmer which is adapted to send programming instructions to said cardiac rhythm management device.

8. A cardiac rhythm management system including a cardiac rhythm management device and a data correlation unit, said data correlation unit being adapted to receive data from said cardiac rhythm management device and comprising a memory for storing data, a processor for correlating data and an output unit for displaying data, said memory containing a first data and a second data, said first data and said second data being a same type data, said processor correlating said first data and said second data and sending said correlated first and second data to said output unit, said first and second data being simultaneously displayed on said output unit;

wherein said first data is displayed with a third data representing the context in which said first data was collected, and said second data is displayed with a fourth data representing the context in which said second data was collected.

9. The system according to claim 8, wherein said first data is heart rate variability data, said third data includes a time at which said first data was collected, and said fourth data includes a time at which said second data was collected.

10. The system according to claim 8, wherein said third and fourth data include the same type of data.

11. The system according to claim 10, wherein said third and fourth data include at least one of CRM device pacing mode, pacing chamber, lower pacing limit, maximum tracking rate, and atrial-ventricular delay.

13. The system according to claim 12, wherein said first data set is periodically collected data from the cardiac rhythm management device and said second data set is asynchronous data.

14. The system according to claim 13, wherein said first data set is patient activity data, and said second data set includes a time at which an accelerometer response factor of the cardiac rhythm management device was changed.

15. The system according to claim 14, wherein said first data set is the number of shocks in a given time period, and said second data set includes a time at which a ventricular sensitivity of the cardiac rhythm management device was changed.

16. The system according to claim 12, wherein the first and second data sets are displayed over a same time period.

19. The method according to claim 18, wherein acquiring the data set includes acquiring data before and after the stored time such that the effect of the programmed parameter had on the data in the data set is visually displayed.

20. The method according to claim 18, wherein acquiring the data set includes downloading the data set from an implanted cardiac rhythm management device.

21. The method according to claim 18, wherein correlating the data set and the stored time includes graphing the data set versus time and overlaying the stored time on a same graph.

22. The method according to claim 21, wherein outputting the correlated data set and stored time includes assigning the data set and stored time visually different elements on the graph.

23. The method according to claim 18, wherein acquiring the data set includes recording a number of shocks by the cardiac rhythm management device in predetermined time periods;

and correlating the data set and the stored time includes graphing the number of shocks in select time periods versus time and including an indicator of the time at which the parameter change occurred on the same graph.

24. The method according to claim 23, wherein storing the time at which the operational parameter was changed includes recording the time at which ventricular sensitivity of the cardiac rhythm management device occurred.

25. The method according to claim 18, wherein acquiring the data set includes recording patient activity, and storing the time at which the operational parameter was programmed includes a time at which an accelerometer response factor of the cardiac rhythm management device was changed.

26. The method according to claim 18, wherein acquiring the data set includes measuring patient activity with the cardiac rhythm management device as a percentage of time that a patient'"'"'s activity level is above a given threshold value.
