Abstract

U radu je opisan algoritam za detekciju atrijske fibrilacije primjenom Hilbertove transformacije. Detektirani su R zupci i izlučene su značajke atrijske fibrilacije. Algoritam započinje prikazom EKG signala, te dalje slijedi filtriranje, podjela na odsječke, deriviranje, Hilbertova transformacija, detekcija R zubaca i ekstrakcija značajki atrijske fibrilacije pod koje se podrazumijeva srčani ritam, detekcija P valova i varijabilnost. U svrhu prikaza postignutih rezultata razvijeno je korisničko sučelje u MATLAB-u.

Abstract (english)

The paper describes an atrial fibrillation detection algorithm based on Hilbert transform. The R peaks were detected and atrial fibrillation features were excreted. The first step of the algorithm includes the display of ECG signals, then further along is filtration, sectioning, Hilbert transform, R peak detection and finally feature extraction which are heart rate, variability and detection of the P wave. For the purposes of presenting results, a user interface has been developed in MATLAB.
