Wearable medical device response mechanisms and methods of use

A system for providing a patient with arrhythmia treatment that is worn partially under clothing of the patient, comprising:

• an arrhythmia monitoring and treatment assembly configured to be worn on a torso of the patient and discreetly extending from a skin surface of the patient, the arrhythmia monitoring and treatment assembly comprising a housing having a tallest height extending no more than 10 cm from the skin surface of the patient,
• wherein the arrhythmia monitoring and treatment assembly further comprises at least one pad configured to be adhesively attached to the patient's torso, and the housing is configured to be mounted on the at least one pad, and
• wherein the arrhythmia monitoring and treatment assembly is configured for providing therapy to the patient on detecting one or more arrhythmia conditions of the patient;
• first two user response buttons disposed on the housing of the arrhythmia monitoring and treatment assembly having the tallest height extending no more than 10 cm from the skin surface of the patient at a first location on the patient's torso such that the first two user response buttons are configured to be concealed under the clothing of the patient, wherein the first two user response buttons are disposed on the housing such that the patient must press the first two user response buttons simultaneously with two fingers;
• a second at least one user response button configured to be worn on a second location of the patient's body at a location other than the torso such that the second at least one user response button is accessible to the patient;
• and
• a processor disposed in the arrhythmia monitoring and treatment assembly configured to
• analyze an ECG signal of the patient received via the arrhythmia monitoring and treatment assembly to detect the one or more arrhythmia conditions of the patient,
• cause the arrhythmia monitoring and treatment assembly to provide a warning of an impending therapy to be delivered to the patient in response to a detected one or more arrhythmia conditions of the patient,
• receive from at least one of the first two user response buttons or the second at least one user response button a user input in response to the warning of the impending therapy, wherein the user input comprises at least one of
• the first two user response buttons being pressed simultaneously;
• or
• the second at least one user response button being pressed for a threshold duration and released;
• and
• wherein if the at least one of the first two user response buttons or the second at least one user response button is pressed for longer than the threshold duration without release, the processor is configured to prompt the patient to indicate consciousness by providing another user input via the housing of the arrhythmia monitoring and treatment assembly;
• and
• cause the arrhythmia monitoring and treatment assembly to suspend the impending therapy in response to the received user input from the at least one of the first two user response buttons or the second at least one user response button.
