This filtering code is applicable to the MIT BIH Arryhthmia database. For other databases to achieve optimal filtering some tweaking is needed to "preprocess_window_ecg.m".
Uses various functions to extract certain features from the ECG Signal. (NOT all features extraction code is given-: Most of it).
Based on my research paper published at IEEE GCAT
R. Sanghavi, F. Chheda, S. Kanchan and S. Kadge, "Detection Of Atrial Fibrillation in Electrocardiogram Signals using Machine Learning," 2021 2nd Global Conference for Advancement in Technology (GCAT), 2021, pp. 1-6, doi: 10.1109/GCAT52182.2021.9587664.
THE NAME HAS BEEN CHANGED. IT IS NOW OFFICIALLY A TOOLBOX.
