A device to evaluate the arterial wall stiffness using pulse wave velocity measurements is described. The device uses probes to record the pulse wave at different locations on the body. Automatic calculation of the time delay between the proximal and distal waves is performed. Based on the pulse wave velocity values and the brachial pulse pressure, an estimation of the central (aortic) pulse pressure is calculated.
