An electromedical
implant includes a measuring
signal generator, an impedance measuring unit to determine the impedance of human or animal tissue, a
control unit which, for controlling the measuring
signal generator and the impedance measuring unit, is at least indirectly connected to the measuring
signal generator and to the impedance measuring unit, as well as an
electrode arrangement comprising at least two electrodes which can be directly or indirectly connected or at least temporarily connected to the measuring
signal generator and to the impedance measuring unit, or to a connection for such an
electrode arrangement. The measuring
signal generator is designed to generate and emit a
current pulse or a series of current pulses, and the
control unit is designed at a specific point in time to cause the measuring
signal generator (to generate and emit a
current pulse, and to cause the impedance measuring unit to measure the
voltage that is present between the electrodes connected to the measuring signal generator and the impedance measuring unit after the passing of at least two time periods of different length that start with commencement of the
current pulse being emitted and end before the end of emitting the current pulse, and to issue a
voltage value which in each case represents the measured
voltage.
