Medical device configured to test for user responsiveness

A wearable defibrillator system, comprising:

• at least one of a harness, vest, and belt configured to be worn by a patient;
• at least one sensing electrode configured to sense an electrocardiogram signal of the patient;
• at least one treatment electrode disposed in the at least one of the harness, vest, and belt, the at least one treatment electrode configured to provide treatment to the patient;
• at least one controller operatively connected to the at least one sensing electrode and the at least one treatment electrode, the at least one controller being configured
• to receive the electrocardiogram signal of the patient,
• to determine, based on at least the electrocardiogram signal of the patient, whether the patient is experiencing a cardiac arrhythmia, and
• to provide at least one prompt to elicit a response from the patient in response to determining that the patient is experiencing the cardiac arrhythmia;
• and
• a response device configured to wirelessly communicate with the at least one controller to cause the at least one controller to withhold treatment to the patient via the at least one treatment electrode in response to input from the patient.

A method of testing responsiveness of a patient wearing a defibrillator comprising:

• sensing an electrocardiogram signal of the patient wearing the defibrillator;
• determining whether the patient is experiencing a cardiac arrhythmia based on at least the electrocardiogram signal of the patient;
• providing at least one prompt to elicit a response from the patient in response to determining that the patient is experiencing the cardiac arrhythmia;
• providing treatment to the patient via at least one treatment electrode in response to determining that the patient is experiencing the cardiac arrhythmia and that no response is provided;
• and
• wirelessly communicating the response to at least one controller of the defibrillator to cause the defibrillator to withhold treatment to the patient via the at least one treatment electrode in response to the patient providing the response.
