First results obtained with an epicardial screw-in electrode.

A description is given of the introduction of an epicardial screw-in electrode (Medtronic, model 6917) by the infrasternal approach in 22 patients with severe cardiac conduction disorders. Special attention is given to the surgical technique, the electrode and the measurement of the threshold value. Comparison of the various techniques of pacemarker implantation leads to the conclusion that this method of treatment offers many advantages.
