Key result
Wave speed and X-wave energy were significantly higher in the brachial and radial arteries compared with the carotid artery (P<0.05 and P<0.001, respectively).
Population
21 normal adult subjects (14 men and 7 women, mean age 44 +/- 6 yr)

Wave-intensity analysis demonstrates significant differences in wave speed and energy patterns between central and peripheral arteries, providing a noninvasive method to study ventriculo-arterial interactions.
Zambanini et al. (2005) conducted a cross-sectional in Healthy subjects (n=21). Brachial and radial arteries vs. Carotid artery was evaluated on Wave speed and wave energy (p=<0.05). Wave speed and X-wave energy were significantly higher in the brachial and radial arteries compared with the carotid artery (P<0.05 and P<0.001, respectively).
