The phonocardiogram exercise test

IEEE Engineering in Medicine and Biology Magazine, 1999
Cardiovascular disease is the leading killer and the major cause of disability in adults. Detection and analysis of heart sounds is an important (and economical) method that can be used to determine the state of the heart and great vessels. In this article we present a newly developed technique for detecting cardiac reserve in both healthy and diseased

Automatic segmentation for neonatal phonocardiogram

2021 43rd Annual International Conference of the IEEE Engineering in Medicine & Biology Society (EMBC), 2021
This work addresses the automatic segmentation of neonatal phonocardiogram (PCG) to be used in the artificial intelligence-assisted diagnosis of abnormal heart sounds. The proposed novel algorithm has a single free parameter - the maximum heart rate. The algorithm is compared with the baseline algorithm, which was developed for adult PCG segmentation ...

Computer aided analysis of phonocardiogram

Journal of Medical Engineering & Technology, 2007
In the present paper analysis of phonocardiogram (PCG) records are presented. The analysis has been carried out in both time and frequency domains with the aim of detecting certain correlations between the time and frequency domain representations of PCG. The analysis is limited to first and second heart sounds (S1 and S2) only.

The exercise phonocardiogram in mitral stenosis

American Heart Journal, 1966
Abstract Eighteen of 20 patients with moderate and severe mitral stenosis had positive exercise phonocardiographic tests. None of the 10 patients with mild stenosis had a positive test. Pour of 7 patients who had positive tests preoperatively and were retested after mitral valvotomy had negative tests.

The pericardial friction rub in the phonocardiogram

The American Journal of Cardiology, 1959
Abstract The sound phenomena caused by pericarditis are discussed in regard to their acoustical qualities and their peculiarities, as demonstrated in the phonocardiogram. 1. 1. Pericardial murmurs are predominantly of high frequency, but may also contain vibrations of low frequency. 2. 2. Their amplitude varies considerably. 3. 3.

Noise detection in smartphone phonocardiogram

2017 IEEE International Conference on Acoustics, Speech and Signal Processing (ICASSP), 2017
This paper presents a demo proposal of a standalone smartphone application that can automatically analyse the signal quality of PCG, as it is recorded on a low-cost smartphonebased digital stethoscope. Features, related to the inherent pattern of the autocorrelated signal envelope, have been used for classifying and discarding the noisy portions from a
