The pulse wave is a physiological phenomenon, observable and measurable in the arterial system during blood circulation. During one heart systole a certain blood volume is expelled.ulse wave velocity analysis is a classic index of aortic stiffness and is a predictor of cardiovascular mortality in hypertensive cases. Since aortic pulse wave velocity is dominantly influenced by age, this finding may be of major importance for the evaluation of cardiovascular risk in the elderly.
