Abstract

A partially obstructed latex tube was used to model a stenosed artery. The frequency spectrum contains peaks corresponding to the resonant frequencies of the tube. Resonant peaks were also observed in the spectra of the Korotkoff sounds from the brachial artery. The resonant peaks are related to the geometry and elasticity of the artery and the surrounding tissue. Some useful diagnostic information about the state of the arteries is therefore likely to be obtained from the spectral analysis of arterial sounds.

Sommaire

On a utilisé un tube de latex obturé partiellement pour modeler une artère sténosée et on a déterminé le spectre de fréquences du son engendré par turbulence dans le tube modèle. Le spectre contient des crêtes correspondant aux fréquences de résonance du tube. Des crêtes de résonance ont été également observées dans le spectre des sons de Korotkoff provenant de l'artère brachiale. Ces pointes de résonance sont liées à la configuration et à l'élasticité de l'artère et des tissus environnants. C'est pourquoi l'analyse spectrale des sons artériels est susceptible de fournir des renseignements diagnostiques utiles sur l'état des artères.

Zusammenfassung

Eine teilweise behinderte Latexröhre wurde als Modell für eine verengte Arterie verwendet. Das Frequenzspektrum wurde aus Tönen festgelegt, die durch Wirbelstrom in der Modellröhre erzeugt wurden. Das Spektrum enthält Spitzen, die den Resonanzfrequenzen der Röhre entsprechen. Die Resonanzspitzen wurden ebenfalls in den Spektren von Korotkoffschen Geräuschen der Armarterie beobachtet. Die Resonanzspitzen stehen in Bezug zur Form und Elastizität der Arteire und zum umgebenden Gewebe. Man kann daher wahrescheinlich durch die Spektralanalyse der Arteriengeräusche nützliche diagnostische Angaben über den Zustand der Arterier erhalten.
