The control circuit (50) is designed to establish a potential difference between the two electrodes (30; 40), so that a direct current (55) can flow between the two electrodes (30; 40). One of the electrodes (30) is a coil electrode with a maximum length that is pre-determined by the distance between the tricuspid valve and the end of the right ventricle lying opposite the tricuspid valve and the pulmonary valve. The counter-electrode (40) can be a coil electrode for the coronary sinus, or a plate electrode that can be attached to the exterior of the left ventricle. ## Claims ### Claim 1 An implantable direct-current electrode assembly comprising a first implantable electrode, a second implantable electrode, and a control circuit adapted to deliver a direct current, wherein the first implantable electrode and the second implantable electrode are electrically connected to the control circuit via a respective supply line, wherein the control circuit is designed to establish a potential difference between the first implantable electrode and the second implantable electrode, such that a direct current flows between the first implantable electrode and the second implantable electrode, wherein the first implantable electrode is a coil electrode configured to be positioned in the right ventricle between the tricuspid valve and the end of the right ventricle opposite the tricuspid valve and pulmonary valve, wherein the second implantable electrode is a surface electrode to be fastened at the exterior of the left ventricle, and wherein the direct current is a constant non-pulsing direct current. ### Claim 2 (depends on 1) The implantable direct-current electrode assembly as claimed in claim 1, wherein the electrical connection between the first implantable electrode and the control circuit, as well as between the second implantable electrode and the control circuit are provided as insulated, single-conductor lines. ### Claim 3 (depends on 1) The implantable direct-current electrode assembly as claimed in claim 1, wherein the first implantable electrode comprises an electrode core and one or more windings which are wound about the electrode core, wherein the electrode core is produced from electrically insulating material, wherein the supply line of the first implantable electrode comprises an insulating sheath and which electrode core is connected integrally to the insulating sheath of the supply line of the first implantable electrode. ### Claim 4 (depends on 3) The implantable direct-current electrode assembly as claimed in claim 3, wherein the electrode core of the first implantable coil electrode has a distal end which is blunt and extends past the end of the winding(s). ### Claim 5 (depends on 3) The implantable direct-current electrode assembly as claimed in claim 3, wherein the electrode core of the first implantable electrode has a distal end which is composed of a plurality of free ends protruding from one another and extending past the end of the winding(s). ### Claim 6 (depends on 5) The implantable direct-current electrode assembly as claimed in claim 5, wherein each free end of the plurality of free ends taper to a point. ### Claim 7 (depends on 5) The implantable direct-current electrode assembly as claimed in claim 5, wherein each free end of the plurality of free ends are hook-shaped. ### Claim 8 A method for arranging an implantable direct-current electrode assembly comprising a first implantable electrode, a second implantable electrode, and a control circuit adapted to deliver a direct current, wherein the first implantable electrode and the second implantable electrode are electrically connected to the control circuit, wherein the control circuit is designed to establish a potential difference between the first implantable electrode and the second implantable electrode, such that a direct current flows between the first implantable electrode and the second implantable electrode, wherein the first implantable electrode is a coil electrode configured to be positioned in the right ventricle between the tricuspid valve and the end of the right ventricle opposite the tricuspid valve and pulmonary valve, and wherein the second implantable electrode is a surface electrode configured to be fastened at the exterior of the left ventricle, wherein the surface electrode is adapted to be applied to the side corresponding to the left ventricle, such that a triangular prism-shaped volume is defined between the first implantable electrode and the second implantable electrode, through which volume current flows when direct current is flowing between the first implantable electrode and the second implantable electrode, and wherein the direct current is a constant non-pulsing direct current.
