Figure 6
Left graphs: Temporal evolution of the twist angle calculated from rotational velocities in all three slices and the torsion angle Φ torsion = Φ Apex – Φ Base . Standard deviations are only shown for the basal slice for better visualization purposes but were comparable for mid and apical slices. The circles indicate the early systolic phase, which depicts opposite twists between mice and rabbits / humans. Right graphs: The basal and apical maximum twist angle and the maximum torsion angle (apex - base) for the epi- and the endocardium. Significance between compartments are indicated by * (p < 0.05) and ** (p < 0.001).
