[Computer-aided reading of ECG (author's transl)].

W Koenig, G Linden

    Medizinische Klinik
    |January 19, 1979
    PubMed
    Summary

    Computer-aided analysis of electrocardiograms (ECGs) in 1800 patients showed high accuracy. This system achieved 90% correct interpretations, demonstrating its potential for efficient cardiovascular diagnostics.

    Area of Science:

    • Cardiology
    • Medical Informatics
    • Biomedical Engineering

    Context:

    • Evaluation of a computer-aided system for reading 12-lead scalar electrocardiograms (ECGs).
    • Study involved 1800 cardiovascular patients.
    • Utilized an IBM tracing and processing system with the Bonner analysis program.

    Purpose:

    • To assess the accuracy and reliability of computer-aided ECG interpretation.
    • To determine the rate of correct, false positive, and false negative readings.

    Summary:

    • ECG data underwent analog-to-digital conversion and storage on floppy disks.
    • Data transfer to an IBM computer in Munich occurred overnight via telephone for cost efficiency.
    • Cardiologist review indicated approximately 90% correct interpretations.
    • False negative readings were observed in 6% of cases, with nearly 1% false positives.
    • Technical issues accounted for the remaining discrepancies.

    Impact:

    • Demonstrates the feasibility of remote, computer-assisted ECG analysis.
    • Highlights the system's potential to improve diagnostic efficiency in cardiology.
    • Identifies areas for technical improvement to minimize errors and optimize performance.
