Volume-time curves (A), torsion shear angle-time curves (B) and torsion shear angle-volume$\left(\widehat{\mathbf{\phi }}\widehat{\mathbf{V}}\right)$curves (C) for the HTN and control groups. Data are mean ± SE. Early filling rate is significantly decreased in HTN with a higher peak systolic torsion shear angle compared with controls. HTN $\widehat{\phi }\widehat{V}$ curve slightly shifts to the left of the control $\widehat{\phi }\widehat{V}$ curve with a steeper early diastolic arm (indicated by blue arrow vs. green arrow) vs. controls.
