A cardiological apparatus is provided having a sensor (1) for picking up electrical signals from a heart and a signal processor connected to the sensor (1) and which is adapted to process signals received from the sensor (1) and includes a pre-processor, wherein the processor includes a reference time generator (8) which is adapted to output a time signal upon the occurrence of a periodically recurring signal feature, averaging features (11, 12, 22, 6) which are adapted to form a signal portion which is averaged over a plurality of signal portions between each two time signals, an average store (7) which is adapted to store the average values, a parameter determining feature (9), and scatter value determining features (31) which are adapted to output a scatter value for time-successive signals.
