[Experimental and clinical employment of an endovenous-myocardiac screwing electrode (author's transl)]

A common postoperative complication following transvenous endocardial pacemaker implantation is the dislodgement and displacement of the electrode. Following trial of a new endovenous-myocardiac screwing electrode in dogs we have tried this electrode since December 1976 on 105 patients, of which 84 cases were implanted primarily and 21 secondarily. The average stimulation threshold was 0.7 V at a pulse width of 1 ms. 6 patients had complications. By making a judicious use of this electrode the rate of electrode dislodgement can be reduced appreciably.
