Systems and methods for behaviorally responsive signal detection and therapy delivery
First Claim
1. A method for operating a leadless cardiac pacemaker implanted into a patient, the patient having two or more predefined behavioral states including a first predefined behavioral state and a second predefined behavioral state, the method comprising:
- the leadless cardiac pacemaker detecting a change in the behavioral state of the patient from the first predefined behavioral state to the second predefined behavioral state, and in response, the leadless cardiac pacemaker changing a sampling rate of a sensor signal generated by a sensor of the leadless cardiac pacemaker from a first sampling rate to a second sampling rate;
the leadless cardiac pacemaker using the sampled sensor signal at the second sampling rate to determine an updated pacing rate of the leadless cardiac pacemaker; and
the leadless cardiac pacemaker providing pacing to the patient at the updated pacing rate.

Abstract
Systems, devices, and methods for adjusting functionality of an implantable medical device based on posture are disclosed. In some instances, a method for operating a leadless cardiac pacemaker implanted into a patient, where the patient has two or more predefined behavioral states, may include detecting a change in the behavioral state of the patient, and in response, changing a sampling rate of a sensor signal generated by a sensor of the leadless cardiac pacemaker. In some embodiments, the method may further include using the sampled sensor signal to determine an updated pacing rate of the leadless cardiac pacemaker and providing pacing to the patient at the updated pacing rate.
