An electrical lead equipped with cathode and anode active succession electrodes for positioning in the vicinity of the His bundle tissue. The lead includes a lead body for carrying conductors coupled between electrodes located at or near the distal lead end and a connector assembly located at the proximal lead end for connecting to an implantable pacemaker. The electrode is shaped, at the distal end, for positioning and attachment in the His bundle and branches thereof, cathode and anode electrodes co-extensive with the lead body. The cathode and anode electrodes may be helical screw-in type or equivalent electrodes adapted for secure fixation deep within the His bundle tissue or the tissue in the vicinity of the His bundle.
