    Area of Science:

    • Biomedical Engineering
    • Signal Processing
    • Cardiology

    Background:

    • Electrocardiograms (ECGs) are crucial for diagnosing heart conditions.
    • Detecting subtle and significant ECG waveform changes is vital for accurate arrhythmia identification.
    • Automated analysis of ECG data can improve diagnostic efficiency.

    Purpose of the Study:

    • To develop and evaluate an algorithm for detecting ECG changes using Fourier transform analysis.
