Abstract

Claims (31)

1. A system comprising:

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

at least one lead configured to electrically couple with the pulse generator, the at least one lead including an electrode; and

a controller configured for:

detecting a heartbeat of a patient based on initial sensor data from one or more sensors;

determining, in real time, that a therapeutic electrical pulse to the heart of the patient is not needed;

continuing to gather additional data from one or more sensors over a period of time;

determining, based on the additional data, that the therapeutic electrical pulse was actually needed; and

overruling the determination that the therapeutic electrical pulse was not needed and delivering a therapeutic electrical pulse to the heart of the patient.

2. The system of claim 1 , wherein the period of time is 10% of a previous R-R interval.

3. The system of claim 1 , wherein the period of time has a set maximum to ensure pacing is not inhibited for a clinically undesirable duration.

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

determining that a therapeutic electrical pulse has not been delivered for at least a preset period of time;

providing a first-pace delay prior to delivery of the therapeutic electrical pulse;

acquiring further data from the one or more sensors over the first-pace delay; and

delivering the therapeutic electrical pulse after the first-pace delay.

5. The system of claim 4 , wherein the preset period of time is 10 minutes, and the first-pace delay is 100 ms.

6. A non-transitory, machine-readable medium storing instructions which, when executed by at least one programmable processor, cause the at least one programmable processor to perform operations comprising:

detecting a heartbeat of a patient based on initial sensor data from one or more sensors;

determining, in real time, that a therapeutic electrical pulse to the heart of the patient is not needed;

continuing to gather additional data from one or more sensors over a period of time;

determining, based on the additional data, that a therapeutic electrical pulse was actually needed; and

overruling the determination that the therapeutic electrical pulse was not needed and delivering a therapeutic electrical pulse to the heart of the patient.

7. The machine-readable medium of claim 6 , wherein the period of time is 10% of a previous R-R interval.

8. The machine-readable medium of claim 6 , wherein the period of time has a set maximum to ensure pacing is not inhibited for a clinically undesirable duration.

9. The machine-readable medium of claim 6 , the operations further comprising:

determining that a therapeutic electrical pulse has not been delivered for at least a preset period of time;

providing a first-pace delay prior to delivery of the therapeutic electrical pulse;

acquiring further data from the one or more sensors over the first-pace delay; and

delivering the therapeutic electrical pulse after the first-pace delay.

10. The machine-readable medium of claim 9 , wherein the preset period of time is 10 minutes, and the first-pace delay is 100 ms.
