A method of implanting a permanent pacemaker bipolar lead apparatus comprising positioning a first electrode, connected to one pole of the pacemaker, in a chamber of the heart adjacent the interior surface of the heart muscle, and positioning a second electrode, connected to the other pole of the pacemaker, adjacent the exterior surface of the heart muscle so as to overlie the first electrode, so that upon operating the pacemaker substantially all electric current from the pacemaker flows through the heart muscle. An implantable bipolar lead apparatus for a permanent pacemaker comprising a negative electrode including a recess cavity in the forward end thereof, positionable in a chamber of the heart adjacent the interior surface of the heart muscle, a first conductive cable connected at one end to the negative electrode and connected at the other end to the negative pole of the pacemaker, a positive electrode comprising a plate portion for fixing to the body tissue and a penetrating shaft portion extending from the plate portion including a recess cavity in the end thereof, positionable adjacent the exterior surface of the heart muscle overlying the negative electrode, and a second conductive cable connected at one end to the positive electrode plate and connected at the other end to the positive pole of the pacemaker, operable so that upon operation of the pacemaker substantially all electric current from the pacemaker flows through the heart muscle.
