Figure 5.

Schematic representation of the effect of reflected wave propagation on ventricular segments, demonstrating a greater influence of reflected aortic pressures waves on septal segments which are in continuity with the aorta, compared with lateral segments which are not in direct continuity. The arrows (a) shows an upright notch in early diastole corresponding to propagation of the reflected wave on left ventricular segments. The graphs represent average values for all volunteers. Positive values show inward motion toward the center of the ventricle, while negative values show outward expansion.

Abbreviations: ED, end diastole; ES, end systole; LV, left ventricle.
