A Novel Approach to Simultaneous Phonocardiography and Electrocardiography During Auscultation
IEEE Access, 2023 The combination of the phonocardiogram (PCG) and the electrocardiogram (ECG) allows the simultaneous evaluation of the heart’s mechanical and electrical conditions and could significantly improve the accuracy of an initial cardiovascular disease ...

Heart sound classification from unsegmented phonocardiograms [PDF]
Physiological Measurement, 2017 Most algorithms for automated analysis of phonocardiograms (PCG) require segmentation of the signal into the characteristic heart sounds. The aim was to assess the feasibility for accurate classification of heart sounds on short, unsegmented recordings.PCG segments of 5 s duration from the PhysioNet/Computing in Cardiology Challenge database were ...

Dynamic Changes in Fourth Heart Sound in Type 2 Diabetes: Insights From Visualized Phonocardiography and SGLT2 Inhibitor Adjustment. [PDF]
Case Rep MedThe fourth heart sound (S4) is an auscultatory marker of left ventricular diastolic dysfunction (LVDD). Additionally, S4 correlates with atrial function, which is typically impaired in patients with Type 2 diabetes (T2D) but can improve with sodium–glucose co‐transporter‐2 inhibitor (SGLT2i) therapy.

Short-segment heart sound classification using an ensemble of deep convolutional neural networks [PDF]
, 2018 This paper proposes a framework based on deep convolutional neural networks (CNNs) for automatic heart sound classification using short-segments of individual heart beats. We design a 1D-CNN that directly learns features from raw heart-sound signals, and
