Abstract
An external electrode for stimulating a person'"'"'s heart is comprised of a first conductive layer having a first perimetric edge. A second conductive layer is in electrical contact with the first conductive layer and includes a protruding portion extending at least partially outwardly beyond the first perimetric edge of the first conductive layer. A third conductive layer is in electrical contact with both of the first conductive layer and the protruding portion of the second conductive layer. An electrical lead is connected to the first conductive layer.
