Assessment of Left Ventricular Rotation and Torsion with Two-dimensional Speckle Tracking Echocardiography

Currently, STE has limited feasibility in the measurement of LVtor. There was no significant age-related change in LVtor. In LV rotations, basal rotation was affected by the age-related changes in the LV early diastolic filling, whereas apical rotation was mainly related to LV systolic performance.
