2. The cardiac defibrillator of claim 1 , wherein each pad of the first plurality of independently positionable pads is in electrical communication with the other pads of the first plurality of independently positionable pads via the one or more first leads.

3. The cardiac defibrillator of claim 1 , wherein each pad of the first plurality of independently positionable pads is configured to directly attach to the skin of the patient.

4. The cardiac defibrillator of claim 3 , wherein each pad of the first plurality of independently positionable pads comprises an adhesive for directly attaching to the skin of the patient.

5. The cardiac defibrillator of claim 1 , wherein the second electrode comprises a second plurality of independently positionable pads.

6. An electrode assembly comprising:

a first electrode comprising:

a first electrode pad comprising at least one of an adhesive or gel to secure the first electrode pad to the skin of a patient; and

a second electrode pad comprising at least one of an adhesive or gel to secure the second electrode pad to the skin of a patient, the second electrode pad being configured to move independently relative to the first electrode pad to permit the first and second electrode pads to be independently positioned on a patient;

a connector configured to be selectively coupled with a defibrillator power supply, the connector comprising first and second electrical contacts that are configured to be coupled with first and second terminals, respectively, of the defibrillator power supply, the first electrical contact being electrically coupled with each of the first and second electrode pads;

a second electrode comprising:

a third electrode pad electrically coupled with the second electrical contact of the connector; and

visual indicia indicating the first and second electrode pads are associated with the first electrical contact and indicating the third electrode pad is associated with the second electrical contact,

wherein at least one of the first and second electrodes comprises a cathode and the other comprises an anode.

7. The electrode assembly of claim 6 , further comprising a fourth electrode pad electrically coupled with the second electrical contact of the connector, wherein the third and the fourth electrode pads are configured to move independently of each other so as to be independently positioned on a patient.

8. The electrode assembly of claim 7 , wherein the third and fourth electrode pads are integrally joined to each other via a common layer, and wherein the common layer comprises a region of weakness that can be disrupted to effect separation of the third and fourth electrode pads.

9. The electrode assembly of claim 6 , wherein the first and the second electrode pads are electrically coupled with the first electrical contact via separate electrical leads.

10. The electrode assembly of claim 9 , wherein at least a portion of the visual indicia is present on the electrical leads.

11. The electrode assembly of claim 6 , wherein the first, second, and third electrode pads include at least a portion of the visual indicia.

12. The electrode assembly of claim 6 , wherein the first and second electrode pads are integrally joined to each other via a common layer, and wherein the common layer comprises a region of weakness that can be disrupted to effect separation of the first and second electrode pads.

13. The electrode assembly of claim 6 , wherein the first and second electrode pads are selectively detachable from each other.

14. An electrode assembly comprising:

a first electrode comprising:

a first electrode pad comprising a first conductive element and at least one of an adhesive or gel to secure the first electrode pad to the skin of a patient;

a second electrode pad comprising a second conductive element that is separate from the first conductive element and comprising at least one of an adhesive or gel to secure the second electrode pad to the skin of a patient,

a layer of material that defines at least a portion of each of the first and second electrode pads, wherein the layer of material comprises a region of weakness that can be disrupted to effect separation of the first electrode pad from the second electrode pad to permit the first and second electrode pads to be independently positioned on a patient;

a connector configured to be selectively coupled with a defibrillator power supply, the connector comprising first and second electrical contacts that are configured to be coupled with first and second terminals, respectively, of the defibrillator power supply, the first electrical contact being electrically coupled with each of the first and second electrode pads; and

a second electrode comprising:

a third electrode pad electrically coupled with the second electrical contact of the connector,

wherein at least one of the first and second electrodes comprises a cathode and the other comprises an anode.
