Novel phonocardiography system for heartbeat detection from various locations
Scientific Reports, 2023 The paper presents evaluation of the proposed phonocardiography (PCG) measurement system designed primarily for heartbeat detection to estimate heart rate (HR). Typically, HR estimation is performed using electrocardiography (ECG) or pulse wave as one of

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 ...

Systolic ejection murmurs and the left ventricular outflow tract in boxer dogs [PDF]
, 2007 Turbulence of various genesis in the left ventricular outflow tract (LVOT) causes systolic ejection murmurs. The prevalence of murmurs in adult boxer dogs is 50-80%, the majority of which are of low intensity.

Annals of Noninvasive Electrocardiology, Volume 31, Issue 3, May 2026.This study proposes a non‐invasive approach for coronary artery disease (CAD) screening by analyzing diastolic heart sounds using an Empirical Wavelet Transform (EWT). Spectral energies e(2) and e(3) were identified as sensitive indicators of left anterior descending artery (LAD) stenosis severity.

Journal of Intelligent Medicine, Volume 2, Issue 4, Page 169-178, December 2025.Abstract Sudden cardiac death (SCD) remains one of the leading causes of mortality worldwide, with coronary artery disease (CAD) as its predominant underlying condition. However, noninvasive and accessible screening approaches for CAD are still limited.
