    Area of Science:

    • Cardiology
    • Biomedical Engineering
    • Medical Informatics

    Background:

    • Significant investment in computerized ECG interpretation exists.
    • Rationalization of ECG recording, labeling, mounting, and presentation has been overlooked.
    • A need for efficient ECG data management and analysis is apparent.

    Purpose of the Study:

    • To describe a novel system for rationalizing ECG recording, labeling, and presentation.
    • To integrate computer technology for on-line ECG analysis and reporting.
    • To enhance the efficiency and clarity of ECG data handling in clinical laboratories.

    Main Methods:

    • Utilized a PDP8/E computer and modified ink jet ECG recorders.
    • Implemented on-line computer service for ECG at rest, VCG, and exercise ECG.
