Figure 4
Bulls-eye plots for systolic and diastolic radial ( v r , A) and long-axis ( v z , B) peak velocities (mean values of all animals) within the 16 AHA-segments of the three different species. Radial velocities (A) show similar regional distributions of peak velocities whereas more pronounced differences are found for long-axis peak velocities (B) such as more homogenously distributed systolic murine velocities and lower velocities for apical regions in rabbits and humans compared to basal segments.
