at least two sensing electrodes, each sensing electrode comprising a metallic surface permanently disposed in a garment;

at least two therapy electrodes, each therapy electrode having a conductive surface,

wherein each of the at least two therapy electrodes comprises a replaceable receptacle, each replaceable receptacle comprising at least one dose of conductive fluid, and

wherein each replaceable receptacle is configured to release the conductive fluid from the replaceable receptacle and is further configured to be replaced after use, the release of the conductive fluid from the replaceable receptacle configured to decrease impedance between the respective therapy electrode for the replaceable receptacle and skin of a subject,

the garment, wherein the garment is configured to be worn about a torso of the subject, the garment comprising

a fabric that is stretchable and that is at least one of breathable or moisture wicking,

conductive wiring configured to electrically connect the at least two sensing electrodes to the at least one defibrillator component, and

at least two pockets, each configured to house a therapy electrode, wherein each pocket comprises a pocket surface configured to be situated between the therapy electrode and the skin of the subject when the therapy electrode is housed in the pocket, and wherein the pocket surface comprises a mesh comprising a conductive metal to lower impedance between the skin of the subject and the conductive surface of the therapy electrode housed in the pocket,

wherein the at least two pockets are situated in the garment such that, when the at least two therapy electrodes are inserted into the at least two pockets, at least a first therapy electrode is situated against a front of the subject and at least a second therapy electrode is situated against a rear of the subject; and

wherein the at least two sensing electrodes electrically connected to the at least one defibrillator component via the conductive wiring are configured to monitor an ECG of the subject,

wherein the at least two therapy electrodes are configured to be electrically connected to the at least one defibrillator component and configured to provide an electric shock to the subject, and

wherein the garment is configured to house the at least two sensing electrodes and the at least two therapy electrodes electrically connected to the at least one defibrillator component such that, when the wearable monitoring and therapeutic device is positioned on the subject, the wearable monitoring and therapeutic device accommodates the subject's chest size.

2 . The wearable monitoring and therapeutic device of claim 1 , wherein the fabric is moisture wicking.

3 . The wearable monitoring and therapeutic device of claim 2 , wherein the fabric comprises a spandex nylon.

4 . The wearable monitoring and therapeutic device of claim 3 , wherein the fabric of the garment is configured such that, when the wearable monitoring and therapeutic device is positioned on the subject, the garment exerts between 0.050 and 1.70 lbs. of force on the subject.

5 . The wearable monitoring and therapeutic device of claim 3 , wherein the conductive metal of the pocket surface comprises silver.

6 . The wearable monitoring and therapeutic device of claim 1 , wherein the conductive wiring of the garment is configured to stretch to accommodate the subject's chest size.

8 . The wearable monitoring and therapeutic device of claim 1 , wherein the at least two therapy electrodes comprise three therapy electrodes;

wherein the at least two pockets comprise three pockets; and

wherein the three pockets are situated in the garment such that, when the three therapy electrodes are inserted into the three pockets, the first therapy electrode is situated against the front of the subject, the second therapy electrode is situated against the rear of the subject, and a third therapy electrode is situated against the rear of the subject.

9 . The wearable monitoring and therapeutic device of claim 1 , further comprising an alarm module operatively coupled to the at least one defibrillator component and configured to alert the subject of an impending electric shock to be delivered by the at least two therapy electrodes;

wherein the alarm module comprises one or more response buttons configured to be depressed by the subject to indicate that the subject is conscious in response to the alert to the subject of the impending electric shock; and

wherein the alarm module is configured to be disposed on a shoulder strap of the garment.

10 . The wearable monitoring and therapeutic device of claim 9 , wherein the alarm module comprises a user interface.

11 . The wearable monitoring and therapeutic device of claim 10 , wherein the user interface of the alarm module comprises the one or more response buttons.

12 . The wearable monitoring and therapeutic device of claim 11 , wherein the one or more response buttons comprises one response button.

13 . The wearable monitoring and therapeutic device of claim 11 , wherein the alarm module is configured to alert the subject of the impending electric shock via an audio warning.

14 . The wearable monitoring and therapeutic device of claim 11 , wherein the alarm module is further configured to alert the subject of the impending electric shock via a haptic warning.
