    This study introduces a computer program for real-time processing of 8-channel exercise electrocardiograms (ECGs) during stress tests. The system displays ECG complexes and trends, storing key data for analysis.

    Area of Science:

    • Cardiology
    • Biomedical Engineering
    • Computer Science

    Background:

    • Continuous electrocardiogram (ECG) monitoring during exercise stress tests is crucial for diagnosing cardiac conditions.
    • Real-time analysis of ECG data can improve diagnostic accuracy and patient management.
    • Existing systems may lack comprehensive real-time processing capabilities for multi-channel exercise ECGs.

    Purpose of the Study:

    • To present a novel computer program for continuous recording and real-time processing of 8-channel exercise ECGs.
    • To enable visualization of average ECG complexes and trends of morphological and rhythmic parameters during stress tests.
    • To detail the software structure and signal processing for efficient data management.

    Main Methods:

    • Development of a computer program for 8-channel exercise ECG acquisition.
