1. A wearable medical device comprising:
- cardiac sensing electrodes configured for external placement proximate to a patient and to sense cardiac information of the patient;
at least one motion detector configured for external placement proximate to the patient to detect motion of the patient and a body position of the patient; and
a monitoring computer coupled to the at least one motion detector and the cardiac sensing electrodes and configured to monitor the motion and the body position of the patient over a period of time, to detect changes in at least one of an amount of the motion and the body position of the patient over the period of time, and to determine whether the changes in the at least one of the amount of the motion and the body position of the patient over the period of time are indicative of congestive heart failure.

Abstract
A wearable defibrillator consists of a vest (or belt) which is worn by the patient. The device monitors the patient'"'"'s ECG with sensing electrodes and can monitor other patient conditions and in appropriate cases can treat certain conditions. An accelerometer(s) in the wearable defibrillator can allow for the device to determine the position, movements, forces applied to the patient, and/or the device. The device can use a least one patient motion detector generating a signal indicative of patient activity. Analysis of the signal can be indicative of patient activity appropriate for treatment or indication of device condition.

7. A method of diagnosing a patient comprising acts of:
-
providing an externally wearable medical device including a plurality of cardiac sensing electrodes configured to be disposed adjacent the patient in proximity to the patient'"'"'s skin, at least one motion detector configured to detect motion of the patient, and a monitoring computer coupled to the plurality of cardiac sensing electrodes and the at least one motion detector; sensing motion of the patient and a body position of the patient with the at least one motion detector over a period of time; detecting, in the monitoring computer, changes in at least one of the sensed motion and the sensed body position of the patient over the period of time; and determining, in the monitoring computer, whether the changes in the at least one of the sensed motion and the sensed body position of the patient over the period of time are indicative of congestive heart failure. - View Dependent Claims (8, 9, 10, 11)
