Abstract
As is known, the speed of propagation of the pulse wave is of great importance for the diagnosis of the elastic properties of arteries, especially in atherosclerosis. The speed of the pulse wave is determined by the time delay of the pulse in the distal part of the artery. This task can be solved by comparing sphygmograms or piezograms from two sections of the artery, simultaneously filmed or taken simultaneously with the ECG.
