1. An implantable medical electrical lead comprising:
a lead body defining a proximal end and a distal portion, wherein the distal portion of the lead body extends along a longitudinal axis;
a set of defibrillation electrode segments disposed along the distal portion of the lead body, wherein at least a portion of each defibrillation electrode segment of the set of defibrillation electrode segments is configured to assume a curved shape comprising one or more peaks displaced from the longitudinal axis; and
two or more electrodes disposed on the lead body, wherein the two or more electrodes are separate from the set of defibrillation electrode segments, wherein each electrode of the two or more electrodes is disposed along the longitudinal axis of the lead body, wherein a length of each defibrillation electrode segment of the set of defibrillation electrode segments is greater than a length of each electrode of the two or more electrodes, and wherein the two or more electrodes are configured to perform at least one of:
