NCIt definition : The rate at which a pressure wave moves distally through an artery, which is a direct
measure of arterial stiffness. Clinically, this value is calculated by placing two
pressure catheters a known distance apart (pulse wave distance), measuring the pressure
wave's travel time between sensors (pulse transit time), and then dividing the distance
by the transit time.;
Alternative definition : CDISC: The distance traveled by the peak of the ventricular ejection pressure wave
per unit of time.;
