Abstract

Claims (18)

1. A system comprising:

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

a controller configured for:

receiving sensor data from an accelerometer;

filtering the sensor data from the accelerometer to separate outside motion of the patient from actual motion of the patient;

determining a current activity level of the patient utilizing the sensor data;

comparing an ideal heart rate for the current activity level to an actual heart rate of the patient; and

adjusting a rate of the generation of therapeutic electrical pulses based on the comparison.

2. The system of claim 1 , wherein determining the current activity level includes determining patient movement.

3. The system of claim 1 , wherein the controller is further configured for increasing the rate of the generation of the therapeutic electrical pulses when the sensor data indicates an increased current activity level and the actual heart rate falls below the ideal heart rate by a pre-determined range.

4. The system of claim 3 , wherein the rate of the generation of the therapeutic electrical pulses is adjusted only up to a predetermined maximum rate.

5. The system of claim 1 , the controller further configured for reducing the rate of the generation of the therapeutic electrical pulses over time to a lower rate when the sensor data indicates a reduced activity level.

6. The system of claim 1 , the controller is further configured for determining patient respiration.

7. The system of claim 6 , wherein the controller is further configured to increase the rate of the generation of the therapeutic electrical pulses when a respiration rate and/or volume increases without a correlative heart rate increase.

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

identifying a discrepancy between the patient respiration and the current activity level;

analyzing additional sensor signals to assess whether the discrepancy is noise related; and

altering a sensing profile to avoid the discrepancy.
