Phono-spectrographic analysis of heart murmur in children
BACKGROUND More than 90% of heart murmurs in children are innocent. Frequently the skills of the first examiner are not adequate to differentiate between innocent and pathological murmurs. Our goal was to evaluate the value of a simple and low-cost phonocardiographic recording and analysis system in determining the characteristic features of heart murmurs in children and in distinguishing innoc...
متن کاملThe graphic configuration of innocent systolic murmurs.
The systolic murmurs heard in healthy subjects used to be called " functional " murmurs. White et al. (1942) recommended the term " physiologic." Evans (1947) called these murmurs " innocent." Others have called them " incidental,' "' accidental,'' or "' murmurs of unknown origin." The decision that a systolic murmur is innocent usually depends not only on the character of the murmur itself, bu...
متن کاملOn systolic murmurs and cardiovascular physiological maneuvers.
Physiological principles that directly apply to physical diagnosis provide opportune occasions to bring basic science to the bedside. In this article, we describe the effect of cardiac maneuvers on systolic murmurs and how physiological principles apply to the explanation of the changes noted at the bedside. We discuss the effect of Valsalva, squatting, and hand grip maneuvers on different phys...
متن کاملInnocent murmurs and third heart sounds in Black schoolchildren.
Normal auscultatory findings were studied during a heart survey in which 12 050 Black schoolchildren, aged 2 to 18 years, were examined by cardiologists. Physiological third heart sounds were detected in 96 per cent of children, innocent systolic murmurs in 72 per cent, and innocent mid-diastolic murmurs in 0.27 per cent. The term 'innocent systolic murmur" was used for vibratory systolic murmu...
متن کاملA color spectrographic phonocardiography (CSP) applied to the detection and characterization of heart murmurs: preliminary results
BACKGROUND Although cardiac auscultation remains important to detect abnormal sounds and murmurs indicative of cardiac pathology, the application of electronic methods remains seldom used in everyday clinical practice. In this report we provide preliminary data showing how the phonocardiogram can be analyzed using color spectrographic techniques and discuss how such information may be of future...
