An in vivo preparation is described in which the compressed artery under an occlusive blood pressure cuff is shown to possess a dynamic negative-resistance characteristic. In this situation the pressure drop along a segment of artery decreases despite an increase in flow. Such characteristics have been previously observed only in in vitro preparations. Under the appropriate conditions this characteristic permits self-excited and sustained oscillation (relaxations oscillations) of the intraluminal pressure and flow to occur. A plausible model in which the origin of Korotkoff sounds is linked to such self-excited oscillations is described. [ABSTRACT FROM AUTHOR] |
