Abstract
Cardiac abnormalities are disorders in heart function that can be detected through electrocardiogram (ECG) signals. This research uses a frequency domain-based feature extraction method with Fast Fourier Transform (FFT), using ten features which then the data will be classified using machine learning algorithms, such as SVM, Random Forest, Decision Tree, and K-Nearest Neighbors (KNN). Results show that Random Forest has the best performance with 100% accuracy on test data and 83% on validation data. Desicion Tree achieved 100% accuracy (test data) and 75% (validation data), KNN achieved 83% (test data) and 75% (validation data), while SVM only obtained 50% accuracy. The combination of feature extraction and appropriate algorithms proved effective in detecting cardiac abnormalities and can support a faster and more accurate diagnosis process.
