Abstract: A cardiac electrode arrangement is disclosed for use in temporarily pacing the heart of a subject and comprises an electrically-conductive strip surrounded by a layer of biocompatible insulating material, which layer has openings on one face of the strip to permit exposure of a portion thereof for contact with the heart and on the other face removably accommodates and holds the stripped end of a pacer lead in contact with the strip. The electrode may be attached to the heart by clips or a single suture, and the pacer lead can be disconnected from the electrode after use by simply pulling the stripped end from under the insulating layer.
