Method for determining distribution of reflection sites in the arterial system

Nikolaos Stergiopoulos, Jean-Jacques Meister, Nico Westerhof

We developed a new method to determine the location and importance of reflection sites in the arterial system. The method is based on the decomposition of the aortic pressure wave into its forward and backward components, and it provides the reflection pro ...

Bisferiens peaks in the radial artery pressure wave during patent ductus arteriosus in newborn infants: relationship with ascending aortic flow

Nikolaos Stergiopoulos, Nico Westerhof

Previously, we found evidence that bisferiens peaks in the radial artery pressure wave in the newborn infant may suggest the presence of a left-to-right shunt through a patent ductus arteriosus (PDA). The purpose of the present study was to analyze the ori ...

Determinants of stroke volume and systolic and diastolic aortic pressure

Nikolaos Stergiopoulos, Jean-Jacques Meister, Nico Westerhof

We investigated how parameters describing the heart and the arterial system contribute to the systolic and diastolic pressures (Ps and Pd, respectively) and stroke volume (SV). We have described the heart by the varying-elastance model with six parameters ...

On the wave transmission and reflection properties of stenoses

Nikolaos Stergiopoulos, Jean-Jacques Meister

This study is concerned with the wave reflection properties of arterial stenoses. Two theoretical models have been developed for deriving the reflection coefficient: a linear model resulting from the linearization of the pressure drop-flow equation and an ...
