Figure 3From: Left ventricular strain and strain rate by 2D speckle tracking in chronic thromboembolic pulmonary hypertension before and after pulmonary thromboendarterectomy Linear regression plots of change in posterior wall radial strain (left column) and change in circumferential strain (right column) vs. RHC data. Measures of linear fit (R values) are displayed in table 3. (Circ: circumferential).Back to article page
