    This study reviews methods for measuring cardiac cycle complex durations in electrocardiograms (ECGs). It explores mathematical and signal processing techniques to improve the accuracy of these vital diagnostic measurements.

    Area of Science:

    • Cardiology
    • Biomedical Engineering
    • Signal Processing

    Background:

    • Cardiac cycle complex duration is a key diagnostic index in electrocardiogram (ECG) interpretation.
    • A standardized approach for measuring these durations is currently lacking.

    Purpose of the Study:

    • To review existing methods for detecting and measuring the onset and termination of cardiographic complexes.
    • To explore the application of various mathematical and signal processing techniques to cardiac cycle analysis.

    Main Methods:

    • Review of detection and measurement algorithms for cardiographic complexes.
    • Consideration of Fischer mathematical statistics, Wiener filtration, spline approximation, and Kalman filters.
    • Analysis of cardiac cycle pulse patterns based on physiological electrical activity.
