[First clinical experiences with a new atrial pacemaker electrode ("atrial tined J lead") (author's transl)]

First clinical experiences with a new atrial tined J-shaped pacemaker electrode are reported. The electrode was used for permanent atrial stimulation and--together with a ventricular lead--for bifocal stimulation. Implantation technique, stimulation thresholds and complications are described. Advantages and disadvantages of various atrial electrodes are discussed.
