Abstract: A system includes an implantable medical device that includes an accelerometer sensing circuitry. Responsive to one or more of a first signal from the accelerometer satisfying a first threshold or a first heart rate determined from a first set of cardiac activity data satisfying a first heart rate threshold, processing circuitry of the system determines a first posture state based on the first signal. Responsive to one or more of a second signal satisfying a second threshold or a second heart rate determined from a second set of cardiac activity data satisfying a second heart rate threshold, the processing circuitry determines a second posture state based on the second signal. The processing circuitry determines a heart failure risk based on the first posture state and the second posture state and generates output based at least in part on the heart failure risk.
