Smart garment

A non-invasive, wearable, ambulatory device capable of cardiac defibrillation, the device comprising:

• a smart garment configured to be worn about a torso of a patient;
• a plurality of therapeutic electrodes configured to be removably attached to the garment;
• a plurality of polymer-based ECG sensing electrodes configured to provide ECG signals based on skin electrical activity of the patient wearing the smart garment, wherein one or more of the plurality of polymer-based ECG sensing electrodes comprises:
• a plurality of individually conductive polymer coated fibers, wherein each of the plurality of the individually conductive polymer coated fibers comprises a base fiber treated with a conductive polymer fluid disposed along the base fiber, the base fiber being a single fiber and/or multifiber, and
• a conductive polymer coated fiber assembly comprising the plurality of the individually conductive polymer coated fibers arranged in a predetermined configuration;
• and
• a controller in electrical communication with the plurality of therapeutic electrodes and the plurality of polymer-based ECG sensing electrodes, the controller configured to:
• receive the ECG signals;
• determine at least one arrhythmia episode occurring in the patient based on the received ECG signals;
• and
• causing a defibrillation shock to be delivered to the patient via the plurality of therapeutic electrodes as a function of determining the occurrence of the at least one arrhythmia episode.
