Abstract

Urođene srčane bolesti stvaraju velik teret za zdravstveni sustav i odnose mnoge ljudske živote. Srčani šumovi često mogu ukazivati na neku takvu bolest. Fonokardiogram je zapis zvuka srca snimljen digitalnim stetoskopom. Računalnom analizom fonokardiograma i detekcijom srčanih šumova može se pomoći liječnicima kod dijagnoza srčanih bolesti. U ovom radu su ispitana i uspoređena 4 modela strojnog i 17 modela dubokog učenja na temelju uspješnosti detekcije srčanih šumova na skupu podataka CirCor... More DigiScope. Naučeni su modeli koji detektiraju srčane šumove s točnosti od 92 %, odzivom od 85 % i F1 mjerom od 78 %. Less

Abstract (english)

Congenital heart diseases create a great burden on the healthcare system and take many human lives. Heart murmurs can often indicate such a disease. A phonocardiogram is a recording of heart sounds taken with a digital stethoscope. Computer analysis of phonocardiograms and detection of heart murmurs can help doctors diagnose heart diseases. In this paper, 4 machine learning models and 17 deep learning models were tested and compared based on the success of heart murmur detection on the CirCor... More DigiScope dataset. Models were trained to detect heart murmurs with an accuracy of 92 %, recall of 85 % and F1 score of 78 %. Less
