    • Algorithm for predicting valvular heart disease from heart sounds in an unselected cohort 

      Waaler, Per Niklas Benzler; Melbye, Hasse; Schirmer, Henrik; Johnsen, Markus Kreutzer; Dønnem, Tom; Ravn, Johan Fredrik; Andersen, Stian; Davidsen, Anne Herefoss; Aviles Solis, Juan Carlos; Stylidis, Michael; Bongo, Lars Ailo Aslaksen (Journal article; Tidsskriftartikkel; Peer reviewed, 2024-01-24)
      Objective: This study aims to assess the ability of state-of-the-art machine learning algorithms to detect valvular heart disease (VHD) from digital heart sound recordings in a general population that includes asymptomatic cases and intermediate stages of disease progression.<p> <p>Methods: We trained a recurrent neural network to predict murmurs from heart sound audio using annotated recordings ...

    • Audiovisual recordings of breath sounds to standardize nomenclature 

      Andersen, Stian; Einarsen, Raimonda (Master thesis; Mastergradsoppgave, 2014-05-30)
      Lungeauskultasjon har historisk sett vært en viktig del av den kliniske undersøkelsen, men har manglet en felles, faglig terminologi for å beskrive funnene man har gjort. På tross av flere forsøk på forenkling av eksisterende terminologi, viser studier at det fortsatt er stor variasjon i begrepsbruken blant leger, og at det er et behov for standardisering av lungelydsterminologi. European ...

    • Diagnostic accuracy of heart auscultation for detecting valve disease: a systematic review 

      Davidsen, Anne Herefoss; Andersen, Stian; Halvorsen, Peder Andreas; Schirmer, Henrik; Reierth, Eirik; Melbye, Hasse (Journal article; Tidsskriftartikkel; Peer reviewed, 2023-03-24)
      Objective The objective of this study was to determine the diagnostic accuracy in detecting valvular heart disease (VHD) by heart auscultation, performed by medical doctors.<p> <p>Design/methods A systematic literature search for diagnostic studies comparing heart auscultation to echocardiography or angiography, to evaluate VHD in adults, was performed in MEDLINE (1947–November 2021) and ...

    • Interrater and intrarater agreement on heart murmurs 

      Andersen, Stian; Davidsen, Anne Herefoss; Schirmer, Henrik; Melbye, Hasse; Spigt, Marcus; Aviles Solis, Juan Carlos (Journal article; Tidsskriftartikkel; Peer reviewed, 2023-01-04)
      Objective: To investigate interrater and intrarater agreement between physicians and medical students on heart sound classification from audio recordings, and factors predicting agreement with a reference classification.<p> <p>Design: Intra- and interrater agreement study. <p>Subjects: Seventeen GPs and eight cardiologists from Norway and the Netherlands, eight medical students from Norway. <p>Main ...
