Diastole pressure occurs at the time of blood
WebArrival time is calculated as the delay between the onset of the initial pressure rise and the inflection point (T i in Fig. 11.14).T i was proposed to be a surrogate marker of arterial stiffness, under the principle that the reflected wave will return earlier as PWV increases. A meta-analysis by Baksi et al. 120 showed that T i decreased only modestly with age and … WebNormal blood pressure is below 120/80 mm Hg.
