27 kwi 2018 · Metrics. Abstract. Phonocardiogram (PCG) signal represents recording of sounds and murmurs resulting from heart auscultation. Analysis of these PCG signals is critical in diagnosis of different heart diseases.
1 wrz 2023 · The paper presents evaluation of the proposed phonocardiography (PCG) measurement system designed primarily for heartbeat detection to estimate heart rate (HR).
A phonocardiogram (or PCG) is a plot of high-fidelity recording of the sounds and murmurs made by the heart with the help of the machine called the phonocardiograph; thus, phonocardiography is the recording of all the sounds made by the heart during a cardiac cycle.
Phonocardiography is a diagnostic technique that graphically records cardiac acoustic phenomena. 10 Visualization of heart sounds may help in understanding cardiac events . A visual record may also help an inexperienced listener recognize and classify auscultatory findings.
8 paź 2023 · Phonocardiogram (PCG) signals can be used to analyze heart rate characteristics to detect heart health and detect heart-related diseases. In this paper, we propose a method for designing using wavelet analysis techniques and an ensemble of deep learning models from phonocardiogram (PCG) for heart sound classification.
12 maj 2021 · The dynamic visualization of heart structures such as the opening and closing of the aortic and mitral valves is achieved routinely using different ultrasound modalities such as M-mode, Doppler flow imaging, tissue Doppler Imaging (TDI), and speckle tracking.
A phonocardiogram (PCG) plots recordings of a heart sound and murmur during the cardiac cycle, and analysis of a PCG signal is useful in detecting abnormalities of a heart by using time-frequency analysis and classifications of the heart signals (Milani, Emeroylariffion, Silva, & Nanayakkara, 2021).
