Abstract: An epicardiac pacing lead for ventricular or atrial pacing of the heat of a cardiac patient. The epicardiac pacing lead comprises a catheter housing two elongated electrical conductors one end of each of which is adapted for electrical connection to a source of electrical stimulation and the other end of which is connected to a respective stimulating electrode on the catheter. The section of the catheter adjacent the electrodes has a stiffness characteristic which allows the section to be bent manually and to maintain a configuration into which it has been bent while allowing the section to straighten automatically to follow the course of the catheter as it is withdrawn from the body of the patient. The end portion of the section adjacent the electrode is configured so as to provide a compression spring to facilitate location of the epicardiac pacing lead in position.
