Summary: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. A signal pattern memory is provided in this case for storing a signal sequence pattern, which reflects a predetermined sequence of heart activities, a signal sequence memory for storing a sequence of output signals from the atrium and the ventricle sensing means, comparator means for comparing the sequence of output signals to the stored signal sequence pattern and for emitting an output signal if the two coincide, as well as refractory changeover means for adjusting a shortened refractory time for the refractory switching means in dependence on the output signal from the comparator means.
