Zusammenfassung

Mittels einer IBM 7090 werden formale Analysen vonEinthovenschen Extremitätenableitungen durchgeführt. Programme inFORTRAN II werden beschrieben zur

  1. 1.

    Speicherung von Daten auf ein Magnetband

  2. 2.

    graphischen Wiedergabe der digitalisierten Kurven

  3. 3.

    Ermittlung von Richtung und Größe der Momentanvektoren und zu ihrer graphischen Darstellung

  4. 4.

    Errechnung von weiteren Ekg-Parametern und

  5. 5.

    zur Gewinnung von sogenannten Normkurven zur Reduktion der Zahl der Freiheitsgrade.

Die Programme dienen einerseits zur direkten Analyse der Kurven und sind andererseits als Vorarbeiten für eine diagnostische Auswertung von Kurvenmustern gedacht.

Summary

By means of an IBM 7090 formal analyses were made ofEinthoven's extremity leads. Programs inFORTRAN II were described to

  1. 1)

    update ecg-data on magnetic tape

  2. 2)

    reproduce the digitalized curves

  3. 3)

    calculate direction and length of the momentary vector and to print them out by plotting-programs

  4. 4)

    determinate other ecg-parameters

  5. 5)

    draw “normalized” curves in order to reduce the degrees of freedom.

These programs are used for direct analyses as well as for preliminary data processing in order to enable a diagnostical pattern analysis of ecg-curves.
