A pacing lead includes a first pacing cathode coupled to a first
conductor, a second pacing cathode coupled to a second conductor, and a
flexible anode coupled to a third conductor. The flexible anode has a
length less than approximately 10 millimeters and is spaced apart from
and proximal to the first pacing cathode and spaced apart from and distal
to the second pacing cathode. The spacing between the anode and the first
pacing cathode is approximately equal to the spacing between the anode
and the second pacing cathode.
