Wearable medical monitoring device

A wearable defibrillator for use by a patient in monitoring patient movement and cardiac activity and treating the patient, comprising:

• a garment configured to be worn by the patient;
• a plurality of electrocardiogram (ECG) electrodes coupled to the garment and configured to acquire ECG signals from the patient;
• a plurality of therapy electrodes coupled to the garment and configured to treat the patient by delivering one or more therapeutic shocks to a heart of the patient;
• one or more accelerometers configured to detect patient movement;
• a power supply;
• and
• a monitor powered by the power supply, comprising
• a controller operatively coupled to the plurality of ECG electrodes, the plurality of therapy electrodes, and the one or more accelerometers, the controller being configured to
• receive the ECG signals,
• process the ECG signals to detect an arrhythmia condition of the patient,
• receive the detected patient movement,
• process the detected patient movement to determine a body state of the patient during the detection of the arrhythmia condition,
• delay delivery of the one or more therapeutic shocks when the patient's body state changes over a period of time during the detection of the arrhythmia condition, and
• proceed with the delivery of the one or more therapeutic shocks when the patient's body state does not change over the period of time during the detection of the arrhythmia condition.
