1. A cardiac stimulation system, comprising:
an elongate lead body comprising a flexible distal portion and a distal end, a proximal terminal connector and an assembly of insulated conductors extending therebetween;
a fixation member extending distally from the distal end of the elongate lead body and being configured to pierce into a septal wall of a patient's heart and to secure the elongate lead body to the septal wall;
a first cathode electrode formed on the fixation member;
a second cathode electrode formed on the distal end of the lead body, wherein an entirety of the second cathode electrode extends within an inner perimeter of the fixation member, and wherein the second cathode electrode forms a non-piercing active face configured to maintain active external contact with a corresponding outer surface area of the septal wall within the inner perimeter of the fixation member when the fixation member secures the elongate lead body to the septal wall; and
a pulse generator coupled to the terminal connector and configured to deliver cardiac pacing pulses to the first and second cathode electrodes.
