[First clinical experiences with a new transvenous endocardial screw-in lead (author's transl)]

From November 1976 to January 1977 a total of 10 patients were served with a new transvenous endocardial screw-in lead. In every 5 cases the lead was anchored in the right atrium respectively in the right ventricle. The lead presented itself by good biomechanical (flexibility, tension resistance) and bioelectrical properties. Because of its constructural features it was to insert easily and without any complication. Moreover, it could be placed anatomically stable by choice either in the right atrium or ventricle.
