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 method, comprising:

implanting an implantable medical device, the implantable medical device including a housing and electrodes;

programming a memory circuit of the implantable medical device with a first therapy parameter to control an application of a first therapy by the implantable medical device;

storing, in a memory circuit disposed in the housing, a first data set of medical data associated with an application of the first therapy over a first time period for a first duration;

programming the memory circuit with a second therapy parameter to control application of a second therapy, other than the first therapy, by the implantable medical device;

storing, in a memory circuit disposed in the housing, a second data set of medical data associated with an application of the second therapy by the implantable medical device over a second time period of a second duration other than the first duration;

receiving, with an output unit, the first data set and the second data set;

displaying the first therapy parameter, the first data set and the first time period on the output unit; and

simultaneous with displaying the first therapy parameter, the first data set and the first time period on the output unit, displaying the second therapy parameter, the second data set and the second time period on the output unit.

2. The method of claim 1, wherein storing the second data set includes calculating an average rate of the first data set.

3. The method of claim 1, wherein storing the first data set includes acquiring data before and after the second time period such that an effect the second therapy had on the second data set is visually displayed.

4. The method of claim 1, wherein the second data set includes trend information.

5. The method of claim 1, wherein correlating includes transmitting data over a communication network to a correlation data unit.

6. The method of claim 5, wherein transmitting data over a communication network includes transmitting over a global computer network.

7. The method of claim 6, wherein receiving the first data set includes sensing heart events and transmitting the heart events to the correlation data unit.

8. The method of claim 7, wherein transmitting the heart events includes sending the first data over a communication network includes transmitting over a global computer network.

9. A method, comprising:

implanting an implantable medical device, the implantable medical device including a housing and electrodes;

programming a memory circuit of the implantable medical device with a therapy parameter to control an application of a therapy by the implantable medical device;

storing, in a memory circuit disposed in the housing, a first data set of medical data associated with a first patient activity over a first time period of a first duration;

storing, in a memory circuit disposed in the housing, a second data set of medical data associated with the application of the therapy and a second patient activity over a second time period of a second duration that is different than the first duration;

receiving, with an output unit, the first data set and the second data set;

displaying the therapy parameter, the first data set and the first time period on the output unit; and

simultaneous with displaying the therapy parameter, the first data set and the first time period on the output unit, displaying the second data set and the second time period on the output unit.

10. The method of claim 9, including correlating the first data set to the second data set with a correlation data unit.

11. The method of claim 10, wherein storing a first data set relating to patient activity includes storing the first data set in a remote database separate from the correlation data unit.

12. The method of claim 10, wherein correlating the first data set to the second data set includes correlating based on time.

13. The method of claim 10, wherein correlating includes correlating the first data set and the second data set with at least one of the first data set and the second data set being asynchronous data.

14. The method of claim 9, wherein receiving the second data set includes collecting a plurality of data sets periodically or asynchronously.

15. The method of claim 9, wherein displaying includes using hatching to represent a change in the first data set occurring after an event occurring in the second data set.

16. The method of claim 9, wherein displaying includes changing a color to represent a change in the first data occurring after an event occurring in the second data.

17. A system for displaying medical data from an implantable medical device comprising:

a memory containing a plurality of data sets including at least a first data set distinct from a second data set;

a processor connected to the memory, wherein the processor is adapted to correlate the first data set and the second data set; and

an output unit connected to said processor, the output unit to receive the correlated first and second data sets from the processor, the first set and second data set being simultaneously displayed on the output unit;

wherein the first data set is periodically collected and the second data set is asynchronously collected; and

wherein the first data set is associated with a patient activity over a first time period, and the second data set is associated with the patient activity over a second time period.

18. The system of claim 17, wherein the second data set includes trend information associated with the first data set.

19. The system of claim 17, wherein the first time period is one day, and the second time period is one week.

20. The system of claim 17, wherein the first data set includes accelerometer information.
