1. An implantable medical electrical lead comprising:
a lead body, wherein a distal portion of the lead body is configured to assume an undulating configuration defining a longitudinal axis, the undulating configuration defining at least a first peak displaced from the longitudinal axis in a first direction and a second peak displaced from the longitudinal axis in one of the first direction or a second direction opposite the first direction;
a first defibrillation electrode disposed on the first peak and a second defibrillation electrode disposed on the second peak; and
a separate electrode disposed on the distal portion between the first defibrillation electrode and the second defibrillation electrode,
wherein the distal portion is configured to assume a relatively straight configuration,
wherein the longitudinal axis extends through the first defibrillation electrode and the second defibrillation electrode when the distal portion is held within a lumen of a sheath,
wherein the distal portion is biased to assume the undulating configuration when the distal portion is displaced from the lumen of the sheath, and
wherein the separate electrode is disposed along the longitudinal axis when the distal portion assumes the relatively straight configuration and when the distal portion assumes the undulating configuration.
