A cardiac rhythm management device that can comprise a lead and a pulse generator. The lead can comprise lead body, a composite conductor, a stylet guide, two or more electrodes and a proximal connector. The composite conductor can comprise two or more conductors which can electrically couple the electrodes to the proximal connector. The electrodes can be disposed on a distal portion of the lead body and can be longitudinally spaced from one another. The proximal connector can be configured to couple to the pulse generator.
