ABSTRACT:
The invention concerns a pacemaker (52) designed for emitting stimulation impulses to an atrium (20) of a heart (22), with a connection for an atrial electrode wire (14) for emitting electrical impulses to the atrium (20), with an atrial stimulation impulse generator (24) that can be connected to the electrode wire (14) and is designed to generate atrial stimulation impulses that are to be emitted over an electrode wire, with a control unit (38) that is connected to the atrial stimulation impulse generator (24) and designed to trigger the stimulation impulse generator (24) in order to generate and emit atrial stimulation impulses, wherein the control unit (38) is designed in an AF-prevention mode that triggers the stimulation impulse generator (24) in order to generate a stimulation impulse sequence that is suitable for preventing atrial fibrillation (AF). It is characterized by an interval timer (34) that is connected to the control unit (32) and designed to turn the AF-prevention mode on and off according to the time of day and thereby activate or deactivate, in a time-controlled manner, the generation and emission of the stimulation impulse sequences preventing atrial fibrillation.
