Implantable electrode, particularly for implantation in a cardiac ventricle in order to stimulate the cardiac muscle, including an insulated electrode lead and at least one fastening element for fixing the electrode end so as to bring a conductive region forming the stimulation surface of the electrode into contact with body tissue, the fastening element being retracted in the region of the electrode end forming the electrode head so that during the insertion phase it can be accommodated substantially within the outer contour of the electrode head touched by body tissue and, in order to fix the electrode end, the fastening element is arranged to be movable relative to the outer contour of the electrode in such a manner that it comes to lie behind the frontal face of the electrode head laterally outside of the outer contour so as to engage in the body tissue.
