A lead assembly for an implantable medical device. The lead assembly comprises a lead body having a first portion and a second portion. The first portion is adapted for coupling to a pulse generator and the second portion is adapted for implantation in or near a heart. First and second co-radial conductive coils are positioned within the lead body and electrically isolated from each other. The first and second conductive coils include a first and second number of coil turns and the first number is substantially equivalent to the second number. A ring electrode is located at the second portion and a tip electrode is located distal to the ring electrode and coupled to the second conductive coil.
