The foam base layer has a first side and the first conductive layer is centrally located on the base layer. The first conductive layer has a first circuit configured to provide a defibrillation current. The second conductive layer extends at least partially around the first conductive layer on the first side of the base layer. The second conductive layer has a separate second circuit configured to receive an electrical signal. The hydrogel layer covers the first and second conductive layers on the first side of the base layer. The electrode pad additionally includes an electrical connector attached to the first and second conductive layers. The electrical connector is configured for providing a voltage to the first and second conductive layers.
