1. Apparatus for recording electrocardiogram information, comprising:

  • means for reading electrocardiogram waveforms and outputting in binary form;

    memory means for storing the binary form of said electrocardiogram waveforms from said reading and outputting means;

    means for compressing said electrocardiogram waveforms into compressed waveforms, said compressing means reading the binary form of said waveforms from said memory means;

    a recording medium having first, second, and third areas;

    means for recording said compressed waveforms as a plurality of first lines in the first area of said recording medium;

    means for detecting a characteristic point common to said electrocardiogram waveforms, said detecting means reading the binary form of said electrocardiogram waveforms from said memory means;

    means for creating analyzed results based on said electrocardiogram waveforms read by said detecting means, said recording means recording said analyzed results along second lines approximately perpendicular to the first lines for compressed waveforms recorded in the first area, said second lines being recorded in the second area of the recording medium;

    means for selecting a first predetermined number of said electrocardiogram waveforms from a second predetermined number of said lines in the first area of said recording medium and superimposing the selected waveforms in synchronism with the characteristic point of the selected waveforms, said recording means recording the superimposed waveforms in the third area of the recording medium while changing location in the third area for every second predetermined number of lines of the first recording area; and

    preprogrammed means for controlling said reading means, said memory means, said compressing means, said detecting means, said creating means, and said selecting and superimposing means.
