Abstract

Claims (38)

1. A system comprising:

a pulse generator including a housing, the pulse generator configured to generate therapeutic electrical pulses;

a sensor configured to detect electrical signals from a heart of a patient; and

a controller configured for:

receiving a signal from the sensor;

obtaining an average heart rate of the patient based on the signal;

obtaining an instant heart rate of the patient based on the signal;

determining a P-wave expectation window based on the average heart rate and the instant heart rate; and

finding a P-wave in the P-wave expectation window utilizing a template.

2. The system of claim 1 , wherein the instant heart rate is based on a preceding P-P interval.

3. The system of claim 1 , the controller further configured for finding the P-wave by:

sweeping the template through expectation window data from the signal; and

comparing the template to the signal to find a best match between the template and the expectation window data.

4. The system of claim 1 , the controller further configured for initiating an atrioventricular (AV) delay based on timing of the P-wave.

5. The system of claim 4 , the controller further configured for adjusting the AV delay based on the timing of the P-wave.

6. The system of claim 1 , the controller further configured for:

identifying an irregular P-wave interval utilizing the P-wave expectation window; and

altering the generation of the therapeutic electrical pulses based on the identifying of the irregular P-wave interval.

7. The system of claim 6 , the controller further configured for reverting the generation the therapeutic electrical pulses to settings prior to the altering when a regular P-wave interval is identified.

8. A system comprising:

a pulse generator including a housing, the pulse generator configured to generate therapeutic electrical pulses;

a sensor configured to detect electrical signals from a heart of a patient; and

a controller configured to:

receive a signal from the sensor;

obtaining an average heart rate of the patient based on the signal;

obtaining an instant heart rate of the patient based on the signal;

determine an R-wave expectation window based on the average heart rate and the instant heart rate; and

find an R-wave in the R-wave expectation window utilizing a template.

9. The system of claim 8 , wherein the instant heart rate is based on a preceding R-R interval.

10. The system of claim 8 , the controller further configured for finding the R-wave by:

sweeping the template through expectation window data from the signal; and

comparing the template to the signal to find a best match between the template and the expectation window data.

11. The system of claim 8 , the controller further configured for initiating an atrioventricular (AV) delay based on timing of the R-wave.

12. The system of claim 11 , the controller further configured for adjusting the AV delay based on the timing of the R-wave.

13. The system of claim 8 , the controller further configured for:

identifying an irregular R-wave interval utilizing the R-wave expectation window; and

altering the generation of the therapeutic electrical pulses based on the identifying of the irregular R-wave interval.

14. The system of claim 13 , the controller further configured for reverting the generation the therapeutic electrical pulses to settings prior to the altering when a regular R-wave interval is identified.
