Digital processing of phonocardiograms: First results
International Journal of Bio-Medical Computing, 1974Abstract Phonocardiography is the recording of the heart sounds. In this paper, the authors propose a method for phonocardiograms automatic parameterisation. The results of an automatic typological study made on parameterised records are presented.

Effect of Position on the Resting and Postexercise Phonocardiogram
Chest, 1972Phonocardiograms were recorded at the maximum apical impulse in the left lateral decubitus position at rest and after a double Master two-step test in 100 normal subjects, mean age 51, in whom this procedure was previously performed in the supine position.

Phonocardiography in the Horse: 1. The Intracardiac Phonocardiogram
Equine Veterinary Journal, 1979SUMMARYUsing microtransducers, the intracardiac phonocardiogram was recorded in 8 horses from the right heart and in 6 of them also on the left side. All 4 heart sounds were recorded but not in all sites. Their timing was related to pressure events.Systolic ejection murmurs were recorded in both the pulmonary artery and the aorta.

A portable graphical representation tool for phonocardiograms
2009 Annual International Conference of the IEEE Engineering in Medicine and Biology Society, 2009This paper describes a prototype software application to display graphical and editable representations of patient data for use in electronic medical records (EMRs). The application dynamically generates graphics of cardiac and other patient data, and displays or saves them both in graphic and in text formats.

Pole-Zero Modeling and Classification of Phonocardiograms
IEEE Transactions on Biomedical Engineering, 1983Phonocardiography, the analysis of heart sounds, is a noninvasive diagnostic method useful in studying heart valve function. Phonocardiograms (PCG's) of porcine prosthetic heart valves in the aortic position were analyzed by a parametric signal modeling method in order to derive frequency domain features suitable for the classification of the valve ...

Atlas of Pulse Tracings and Phonocardiograms.
Archives of Internal Medicine, 1970The expressed purpose of this atlas of pulse tracings and phonocardiograms is "familiarizing those who are not well acquainted with these valuable adjuncts to the physical, and it provides a set of tracings of didactic value for those involved in teaching or learning the physical signs of heart disease." The author is successful in attaining this goal.

The phonocardiogram and apexcardiogram in patients with ventricular aneurysm
The American Journal of Cardiology, 1968Abstract The phonocardiographic and apexcardiographic findings are presented for 60 patients with established old myocardial infarction, 30 of whom had fluoroscopic evidence of ventricular aneurysm. The data indicate that presystolic gallop (83.4 per cent) and quadruple rhythm (40.0 per cent) are very common in patients with ventricular aneurysm and

Phonocardiogram classification based on MFCC extraction
2017 IEEE International Conference on Computational Intelligence and Virtual Environments for Measurement Systems and Applications (CIVEMSA), 2017In this work, a simple method for separation between normal and abnormal heart sounds (Phonocardiogram) is presented. Mel-Frequency Cepstral Coefficients (MFCC) are extracted from two different datasets of heartbeats. Several Classifiers, such as, Support Vectors Machine (SVM), K-Nearest Neighbors (KNN), Naive Bayes (NB), Classification Tree (CT) and ...
