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.
