1. An externally wearable patient treatment device comprising:
- cardiac sensing electrodes configured for external placement proximate to a patient to sense cardiac information of the patient;
treatment elements configured for external placement proximate to the patient;
at least one motion detector configured to generate a signal indicative of motion of the treatment device; and
at least one controller disposed in the treatment device and coupled to the at least one motion detector, the cardiac sensing electrodes, and the treatment elements and configured to receive the signal indicative of motion of the treatment device and determine whether the treatment device is subjected to a force greater than a predefined acceptable force based on the signal.

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.

19. A method of treatment of a patient including:
-
providing an externally wearable patient treatment device, the externally wearable patient treatment device including cardiac sensing electrodes configured for external placement proximate to the patient to sense cardiac information of the patient, treatment elements 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 treatment device, and at least one processor coupled to the at least one motion detector; sensing motion of the treatment device with the at least one motion detector; and evaluating the motion of the treatment device sensed by the at least one motion detector using the at least one processor to determine whether the treatment device is subjected to a force greater than a predefined acceptable force. - View Dependent Claims (20, 21, 22, 23, 24, 25, 26, 27, 28, 29, 30)
