Claim 14:
15. A wearable defibrillator for providing patient wear compliance information, the wearable defibrillator comprising:
a plurality of electrodes configured to be continuously coupled externally to a patient for an extended period of time, the plurality of electrodes configured to monitor electrical activity on a skin of the patient and provide a therapeutic shock to the patient in response to detection of a cardiac arrhythmia based on the monitored electrical activity;
at least one motion sensor and associated circuitry configured to generate at least one motion signal based upon movement of the patient;
a user interface configured to receive user input indicating that the patient has put on the wearable defibrillator; and
at least one processor operably coupled to the user interface, the plurality of electrodes and the at least one motion sensor and associated circuitry, the at least one processor configured to
receive a control signal from the user interface indicating that the user input has been provided;
after receiving the control signal from the user interface, receive at least one electrical signal based on the monitored electrical activity on the skin of the patient from the plurality of electrodes,
determine a current time of day;
record a wear onset event based on the control signal from the user interface, the at least one electrical signal, the at least one motion signal, and the current time of day, the wear onset event indicating that the patient is wearing the wearable defibrillator,
record a wear offset event based on the at least one electrical signal, the at least one motion signal, and the current time of day, the wear offset event indicating that the patient is not wearing the wearable defibrillator, and
output a graphical representation comprising information regarding the patient's wear compliance based on the recorded wear onset event and the recorded wear offset event.
