Abstract: A wearable defibrillator for use in monitoring patient movement and cardiac activity and treating a patient includes a garment configured to be worn by the patient, treatment electrodes configured to apply an electric current to the patient, and an alarm module configured to provide audio, visual, and haptic notifications. The notifications are configured to indicate that an electric current will be administered imminently and prompt the patient to provide a response input. The wearable defibrillator includes a motion sensor configured to detect motion and body position of a patient, and a controller in electrical communication with the alarm module and the motion sensor. The controller is configured to monitor for the response input after the prompt, determine, based on the detected motion and body position, whether the patient is sleeping, and cause a change in one or more characteristics of the prompt on determining that the patient is sleeping.

Abstract: A method of determining responsiveness of a patient wearing a wearable defibrillator configured to deliver therapy to the patient includes sensing an electrocardiogram signal of the patient wearing the wearable defibrillator via a plurality of ECG sensing electrodes, and determining whether a defibrillation treatment should be provided to the patient via at least one treatment electrode. The method includes causing a user interface to provide a patient prompt from the wearable defibrillator responsive to determining that the defibrillation treatment should be provided to the patient. The method includes receiving a first signal indicative of a first patient response within a time interval, receiving a second signal indicative of a second patient response within the time interval, and withholding the defibrillation treatment to the patient via the at least one treatment electrode in response to receiving both the first signal and the second signal within the time interval.
