Various embodiments concern leads having low peak MRI heating for improved MRI compatibility. Various leads include a lead body having at least one lumen, a proximal end configured to interface with an implantable medical device, and a distal end. Such leads can further include a conductor extending along at least a portion of the lead body within the at least one lumen and a defibrillation coil extending along an exterior portion of the lead body and in electrical connection with the conductor, wherein at least a section of the defibrillation coil is under longitudinal compression. The longitudinal compression can lower peak MRI heating along the defibrillation coil. The longitudinal compression may maintain circumferential contact between adjacent turns of the section of the defibrillation coil.
