Abstract

In this paper, the local propagation characteristics of small vibrations on the arterial wall due to heart beat are investigated. Propagation velocity is obtained by analyzing the small vibrations measured simultaneously at two adjacent points on a vessel wall. From in vitro fundamental experiments, it is confirmed that these local acoustic properties (stiffness) of the wall is evaluated. Through the experiments with the extracted human thoracic aorta, it is found that the local stiffness, which is estimated from the pulse wave velocity (PWV) of the aortic wall is increased with aging.
