Abstract

A method for use in an implantable medical device system, comprising: selecting a first sensing electrode operatively disposed in a first heart chamber; setting a first sensing window corresponding to cardiac electrical events occurring in a second heart chamber; enabling a first sense amplifier coupled to the first sensing electrode during the first sensing window; sensing a first signal corresponding to cardiac electrical events occurring in the second heart chamber during the first sensing window using the first sensing electrode; and transmitting the first signal from an implantable medical device to an external monitor.

Claims

1. An implantable medical device system, comprising:

means for selecting a first sensing electrode operatively disposed along a first heart chamber;

means for setting a first sensing window corresponding to cardiac electrical events occurring in a second heart chamber;

means for sensing a first signal corresponding to cardiac electrical events occurring in the second heart chamber during the first sensing window using the first sensing electrode; and

means for transmitting the first signal from an implantable medical device to an external monitor.

2. The system of claim 19 further including means for delivering a first pacing pulse to the second heart chamber and wherein the means for setting the first sensing window includes means for setting a starting time corresponding to the first pacing pulse.

3. The system of claim 19 further including means for delivering a first pacing pulse to the second heart chamber and means for verifying capture of the second heart chamber using the transmitted first signal.

4. The system of claim 19, further comprising:

means for selecting a second sensing electrode operatively disposed along the second heart chamber;

means for setting a second sensing window corresponding to cardiac electrical events occurring in the first heart chamber;

means for sensing a second signal corresponding to cardiac electrical events occurring in the first heart chamber during the second sensing window using the second sensing electrode; and

means transmitting the second signal from the implantable medical device to the external monitor.

5. The system of claim 22 further including means for delivering a second pacing pulse in the first heart chamber and wherein means for setting the second sensing window includes means for setting a second starting time corresponding to the second pacing pulse.

6. The system of claim 22 further including means for delivering a second pacing pulse to the first heart chamber and means for verifying capture of the first heart chamber using the transmitted second signal.

7. The system of claim 19, further including means for displaying the transmitted first signal.

8. The method of claim 19, further including means for evaluating the performance of the implantable medical device using the transmitted first signal.

9. The method of claim 19, further including means for determining a heart condition using the transmitted first signal.

10. A computer readable medium for storing a set of instructions which when implemented in a system cause the system to:

select a sensing electrode operatively disposed along a first heart chamber;

set a sensing window corresponding to cardiac electrical events occurring in a second heart chamber;

enable a sense amplifier coupled to the sensing electrode during the sensing window;

sense a signal corresponding to cardiac electrical events occurring in the second heart chamber during the sensing window using the sensing electrode; and

transmit the sensed signal from an implantable medical device to an external monitor.

11. The computer readable medium of claim 28 for storing a set of instructions which further causes the system to deliver a pacing pulse and wherein setting a sensing window includes setting a sensing window start time relative to the pacing pulse.

12. The computer readable medium of claim 28 for storing a set of instructions which further causes the system to display the transmitted signal.

13. The computer readable medium of claim 28 for storing a set of instructions which further causes the system to evaluate the performance of the implantable medical device using the transmitted first signal.

14. The computer readable medium of claim 28 for storing a set of instructions which further causes the system to determine a heart condition using the transmitted first signal.
