  • Cardiac pacemaker
    Patent number: 7532930
    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.
    Type: Grant

  • Two-chamber pacemaker
    Patent number: 6192274
    Abstract: Two-chamber pacemaker (100), comprising atrium sensing means (EA, 107) as well as ventricle sensing means (EV, 105) and refractory switching means (100B) for influencing the processing of output signals from the atrium sensing means for a predetermined refractory time, further comprising ventricle stimulation means (106, EV) and a stimulation control unit (100A), which effects a changeover back from a non-atrium synchronous 1:1 operating mode to an atrium-synchronous 1:1 operating mode in dependence on the signals from the atrium sensing means that are influenced by the refractory switching means.
