Automated System for the Detection of Heart Anomalies Using Phonocardiograms: A Systematic Review

IEEE Access
Phonocardiogram (PCG) signals generated by the heart contain information about heart conditions. This review examines how PCG analysis identifies and diagnoses heart issues.

Automated Acute Myocardial Infarction Detection Using Machine Learning From Phonocardiogram

IEEE Access
Early detection of myocardial infarction (MI) is critical due to rapid heart muscle deterioration. Current diagnosis relies on electrocardiogram (ECG) and troponin tests, but troponin tests are accurate only after 12-24 hours.

High-resolution phonocardiogram parameters

IOP Conference Series: Materials Science and Engineering, 2021
Abstract The article describes the results of studying and analyzing phonocardiograms (PCGs) obtained during a physiological experiment with Blu-ray standard equipment. It provides the findings of a spectral and spectral-time analysis for signals with a sampling frequency of 10, 44.1 and 192 kHz.
