Abstract
An electrical lead includes an elongate body having a proximal end portion and a distal end portion, a first electrode disposed adjacent and joined to the distal end portion of the elongate body. Current flow within the first electrode is limited when a predetermined condition occurs, such as the generation of an electromagnetic field having a predetermined frequency range. The medical electrical lead may further comprise one or more second electrodes disposed adjacent the first electrode and joined to the elongate body to shunt current to body tissue when the predetermined condition occurs.
