1. A cardiac rhythm management device, comprising:
- a physiological sensor producing electrical signals associated with a patient'"'"'s physical activity;
a posture sensor producing electrical signals associated with the patient'"'"'s posture; and
a controller coupled to the physiological sensor and the posture sensor, the controller being configured to;
determine a current posture of the patient from the posture sensor signals;
calculate a first estimated caloric expenditure as a function of the electrical signals from the physiological sensor, wherein caloric expenditure is defined as a number that corresponds to the amount of oxygen being consumed by the patient;
calculate a second estimated caloric expenditure as a function of the patient'"'"'s posture; and
,validating the first estimated caloric expenditure with the second estimated caloric expenditure.

Abstract
Systems and methods for estimating caloric expenditure. The systems can include a physiological sensor to measure a patient'"'"'s physical activity, and a posture sensor to measure the patient'"'"'s posture. An estimated caloric expenditure can be calculated based on data from the physiological sensor and the posture sensor. For example, the estimated caloric expenditure can be calculated at least in part based on the posture data. For example, the estimated caloric expenditure can be validated based on the posture data.
