An embodiment includes a cardiac resuscitation system with first and second electrodes in a source electrode pad and a return electrode in a return electrode pad. After the source and return electrode pads are applied to a patient the layperson may put a switch in a first position to create a first electrical path to communicate a first shock between the first and return electrodes via a first vector. If the first shock fails the user may move the switch to a second position to create a second electrical path to communicate a second shock between the second and return electrodes via a second vector. As a result, the system allows a layperson to easily flip a switch to produce a first shock via a first vector and a second shock via a second vector thereby improving therapy outcomes. Other embodiments are described herein. |

| Claim: |
1. A cardiac resuscitation system comprising: first and second surface electrodes included in a single contiguous source electrode pad and a return electrode included in a return electrode pad; a single electronic coupler to electrically couple the first and second electrodes to a shared single therapeutic energy output of an external cardiac resuscitation device; and a switch, coupled to the first and second electrodes, including first and second positions; wherein when the source and return electrode pads are applied to a patient and the switch is in (a) the first position a first electrical path is operable to communicate therapeutic energy through and between the first and return electrodes, via a first vector, without being communicated through the second electrode, and (b) the second position a second electrical path is operable to communicate therapeutic energy through and between the second and return electrodes, via a second vector, without being communicated through the first electrode. |
| Claim: |
2. The system of claim 1, wherein the first and second electrodes are permanently and fixedly located at least 2 inches from one another within the source electrode pad. |
| Claim: |
3. The system of claim 2, wherein: the first vector includes a first direction and a first magnitude; the second vector includes a second direction and a second magnitude; and the first direction is unequal to the second direction. |
| Claim: |
4. The system of claim 3, wherein the first direction is unequal to the second direction by at least 3 degrees. |
| Claim: |
5. The system of claim 3, wherein the first direction is unequal to the second direction by at least 3 degrees when the first and second electrodes are located on the patient's chest and in a single axial plane and the return electrode is located on the patient's side. |
| Claim: |
6. The system of claim 3, wherein the source electrode pad includes an electrical insulator electrically insulating the first electrode from the second electrode. |
| Claim: |
7. The system of claim 1, wherein: the switch includes a third position; and when the switch is in the third position the first and second electrical paths are simultaneously operable to communicate therapeutic energy through and between the first and return electrodes via the first vector and through and between the second and return electrodes via the second vector. |
| Claim: |
8. The system of claim 1 comprising the external cardiac resuscitation device, wherein the external cardiac resuscitation device includes one of an automated external defibrillator (AED), an external defibrillator, and an electrocardiogram monitoring system. |
| Claim: |
9. The system of claim 8 comprising at least one non-transitory machine readable medium comprising instructions that when executed on a processor, which is included in the external cardiac resuscitation device, cause the external cardiac resuscitation device to perform a method comprising: delivering first therapeutic energy to the patient through and between the first and return electrodes; determining the patient has an abnormal heart rhythm after delivering the first therapeutic energy to the patient; based on determining the patient has an abnormal heart rhythm after delivering the first therapeutic energy to the patient, (i) automatically switching the switch from the first position to the second position, and then (ii) delivering second therapeutic energy to the patient through and between the second and return electrodes. |
| Claim: |
10.
