Body tilt alters aortic propagation times in healthy volunteers; supports lower-limb reflection origins of diastolic waves but leaves clinical relevance open.
Does body tilt alter the central aortic pressure pulse and propagation times in young healthy volunteers?
Diastolic waves observed on central aortic pulses reconstructed from radial tonometry correspond at least in part to reflections generated in the lower limbs.
Rotaru et al. (2015) studied this question.
