A medical electrical lead may include a lead body having a proximal end and a distal end, a conductive electrode shaft located near the distal end within the lead body, a coiled conductor extending within the lead body from the proximal end and coupled to a first end of the conductive electrode shaft, and an electrode located near the distal end of the lead body and coupled to an opposite end of the conductive electrode shaft as the coiled conductor. The lead may also include an energy dissipating structure located near the distal end of the lead body and formed from a conductive material that defines a lumen through which a portion of the coiled conductor extends. The portion of the coiled conductor extending through the lumen defined by the energy dissipating structure is formed to provide an interference contact with the energy dissipating structure.
