Noninvasive pulmonary artery wave intensity analysis in pulmonary hypertension [PDF]
American Journal of Physiology - Heart and Circulatory Physiology, 2015 Pulmonary wave reflections are a potential hemodynamic biomarker for pulmonary hypertension (PH) and can be analyzed using wave intensity analysis (WIA). In this study we used pulmonary vessel area and flow obtained using cardiac magnetic resonance (CMR)

Determination of wave intensity in flexible tubes using measured diameter and velocity [PDF]
, 2007 Wave intensity (WI) is a hemodynamics index, which is the product of changes in pressure and velocity across the wave-front. Wave Intensity Analysis, which is a time domain technique allows for the separation of running waves into their forward and ...

A new approach to investigate wave dissipation in viscoelastic tubes: Application of wave intensity analysis [PDF]
, 2005 Wave dissipation in elastic and viscoelastic medium has been investigated extensively in the frequency domain. The aim of this study is to examine the pattern of wave dissipation in the time-domain using wave intensity analysis.

Racial Differences in Left Ventricular Mass and Wave Reflection Intensity in Children
Frontiers in Pediatrics, 2020 The burden of heart failure is disproportionately higher in African Americans, with a higher prevalence seen at an early age. Examination of racial differences in left ventricular mass (LVM) in childhood may offer insight into risk for cardiac target ...
