[Current state of treatment of bradycardia with various pacemaker systems].

The present state of knowledge about treatment of bradycardias with pacemakers is presented. Types of pacers as well as their coding, their differential indications for specific conditions and their complications and possibilities of controlling are described. Finally the percutaneous implantation technique for one- and two-chamber-systems with one or two electrodes via the subclavian vein is described as it was first published from this department in 1976.
