[A simple and reliable atrial pacemaker electrode: technique of transvenous implantation and clinical results with a metal hook electrode (author's transl)].

At present only about 1% of all implanted pacemakers are atrial triggered ones, although an indication for them exists in about 77% of cases. This disproportion is due to an overestimate of the difficulties encountered in fixing the electrode. The electrode developed by Irnich has now been modified to provide good fixation for atrial stimulation, as well as recording of atrial potentials. Preliminary results in 20 patients have been favourable. Over a seven-month observation period there have been no instances of dislocation or loss of effective stimulation.
