1. An electrostimulator comprising:

  • one heart-working electrode adapted to be implanted in tissue adjacent to a heart;

    an output connection for connection to the one working electrode;

    a test signal generator having an output connected to the output connection for generating one of a pulse-shaped and periodically changeable test signal and feeding the signal to the output connection for stimulating the heart;

    a first measuring device having an input connected to the output connection for measuring at least one of an electrical voltage present at the output connection and a current flowing over the output connection; and

    an evaluation device having an input connected at least indirectly to the first measuring device for generating an output signal that reflects the working electrode capacity in dependence on at least one of the current and voltage present at the output connection and for determining whether the heart has been stimulated.
