Abstract
A cardiac pacemaker, whose stimulation rate is controlled dependent on an impedance signal acquired between two electrodes, has one of the two electrodes disposed in an atrial electrode catheter and the other electrode being disposed in a separate, ventricular electrode catheter. Catheters carrying only a single electrode can thus be used, thereby avoiding the use of a bipolar electrode catheter. The two electrodes are respectively connected to two different stimulation pulse generators within the pacemaker housing, constructed as a dual chamber pacemaker.
