A bipolar electrode assembly for attachment to heart tissue for use with a pacemaker. The assembly has a hub member with a helical screw-in coil that acts as a first electrode and is used to attach the assembly to the heart tissue. The assembly further comprises a plurality of appendages that extend from the hub member and each have an electrode segment of electrically conductive material. The electrode segment of the appendages can act together as a single second electrode, or alternatively as a separate, independent electrodes, which may selectively be used for pacing or sensing. The electrode segments not only act as electrodes, but also allows heart tissue to grow directly into the conductive material to help secure the assembly to the heart. The assembly also has apertures and grooves for suture connection of the assembly to the heart. Methods of manufacturing the assembly and connecting the assembly to a heart are also described.
