Abstract
Certain embodiments of the present invention disclose an electrostimulator, in particular an atrial cardiac pacemaker, comprising electrode connections which are connected to a stimulation unit for the delivery of stimulation pulses by way of the electrode connections, and a stimulation control unit which is connected to the stimulation unit and adapted to trigger the delivery of stimulation pulses and to determine the strength of the stimulation pulses and for that purpose to deliver a stimulation control signal to the stimulation unit, and a detection unit which is connected to the stimulation control unit and at least indirectly to the electrode connections and adapted to evaluate electrical potentials at the electrode connections and to detect intrinsic (natural, spontaneous) events. The stimulation control unit is adapted to produce a far-field signal if the detection unit detects an intrinsic atrial event within a predetermined far-field coupling interval which begins after triggering of a ventricular stimulation pulse.
