<unk>  <unk>  is a measure of arterial distensibility. It is defined as the<unk>  of the pressure<unk>  produced by ventricular ejection that travels along an arterial segment. It is calculated from the interval between two pressure peaks located at two different positions in the arterial tree. Because of the principle that pressure<unk> s travel faster in less distensible arteries,<unk>  measurement has been considered the best proxy for the assessment of arterial stiffness.
