Recently we developed a non-invasive ultrasound technique, enabling the determination of end-diastolic diameter and distension (increase in diameter during cardiac cycle) over a long time period. Using this technique we test the hypothesis that low-frequency variations derived from non-invasively determined common carotid artery diameter signals are superior to those derived from non-invasively determined arterial pressure to predict heart rate variability, a method used to assess baroreceptor sensitivity. Moreover, we investigate whether the reduced baroreflex sensitivity in the elderly persists after eliminating the influence of the stiffness of the vessel wall and can be attributed to an impairment of the neural baroreflex pathways. |
