The heart is a vital organ responsible for blood circulation throughout the body, delivering oxygen and nutrients to every living cell. Diagnosing and treating medical conditions is important to preserve human life accurately. To achieve this, an electronic stethoscope has been developed to record and analyse heart sounds. This study aims to computationally segment and identify cardiac signals using an envelope-based strategy with reference data, utilising the PASCAL Classifying Heart Sounds Challenge database. The findings indicate that the proposed method for detecting and partitioning the typical cardiac acoustic waveform exhibits a precision rate of 95.30% and an F1-score of 91.00%. The technique is well-suited for application to the two prominent peaks in heart sound signals, namely S1 and S2, which exhibit continuous variation across samples due to differences in auscultatory sites.
Serce jest ważnym narządem odpowiedzialnym za krążenie krwi w całym ciele, dostarczając tlenu i składników odżywczych do każdej żywej komórki. Ważne jest, aby precyzyjnie zdiagnozować i leczyć warunki medyczne w celu zachowania życia ludzkiego. Aby to osiągnąć, opracowano elektroniczny stetoskop, który elektronicznie rejestruje i analizuje dźwięki serca. Celem tego badania jest segmentacja obliczeniowa i identyfikacja sygnałów sercowych przy użyciu strategii opartej na kopercie z danymi referencyjnymi, z wykorzystaniem bazy danych PASCAL Classifying Heart Sounds Challenge. Wyniki wskazują, że proponowana metoda wykrywania i podziału typowej formy fali akustycznej serca wykazuje dokładność 95,30% i wynik F1 91,00%. Technika jest dobrze przystosowana do stosowania do dwóch wybitnych szczytów sygnałów dźwiękowych serca, a mianowicie S1 i S2, które wykazują ciągłe zmiany w próbkach z powodu różnic w miejscach auskultacyjnych.
