Abstract

A method and an apparatus for performing implementing external data into an implantable medical device. A first stress test is performed using an external sensor. External data resulting from the initial stress test is acquired. An external data injection process is performed. The external data injection process includes providing the external data to the implantable medical device. A second stress test is performed, the second stress test being substantially similar to the first stress test. Internal data resulting from the second stress test is acquired. Internal data resulting from the second stress test along with the external data resulting from the first stress test, are processed.

Claims

1. A method for injecting external data into an implantable medical device, comprising the steps of:

performing a first stress test using an external sensor;

acquiring external data resulting from said first stress test;

performing an external data injection process, said external data injection process comprising providing said external data to said implantable medical device;

performing a second stress test, said second stress test being substantially similar to said first stress test;

acquiring internal data resulting from said second stress test; and

processing said internal data resulting from said second stress test along with said external data resulting from said first stress test.

2. The method described in claim 1, wherein the step of performing a first stress test using an external sensor further comprises performing said first stress test on a treadmill.

3. The method described in claim 1, wherein the step of acquiring external data resulting from said initial stress test further comprises acquiring non-physiological data.

4. The method described in claim 3, wherein the step of acquiring external data resulting from said initial stress test further comprises acquiring data from an external accelerometer.

5. The method described in claim 1, wherein the step of performing an external data injection process further comprises:

storing said external data;

transferring said stored external data to an access device capable of communicating with said implantable medical device; and

downloading said external data from said access device into said implantable medical device.

6. The method described in claim 1, wherein the step of acquiring internal data resulting from said second stress test further comprises acquiring data from an internal sensor operatively coupled with said implantable medical device.

7. The method described in claim 6, wherein the step of acquiring internal data resulting from said second stress test further comprises acquiring physiological data.

8. The method described in claim 1, wherein the step of processing said internal data resulting from said second stress test along with said external data resulting from said first stress test further comprises:

blending said internal data with said external data;

calculating a target pacing rate for a delivery of therapy based at least partially upon at least one of said blending of said internal and external data and an initial setpoint therapy target pacing rate;

modifying a therapy delivery rate based upon said target pacing rate; and

calculating a new setpoint therapy target pacing rate as feedback for calculating a subsequent target pacing rate.

9. The method described in claim 8, wherein the step of blending said internal data with said external data further comprises combining real time physiological data with corresponding stored non-physiological data.

10. The method described in claim 1, wherein the step of processing said internal data resulting from said second stress test along with said external data resulting from said first stress test further comprises validating an operation of an implantable medical device.
