Fig. 2From: Detection of right ventricular dysfunction by three – dimensional echocardiography and two - dimensional speckle tracking in breast cancer patients receiving anthracycline- based chemotherapyTracking of the 6 – segment region of interest (ROI) in the endocardial border of the right ventricle (RV) from the apical four–chamber view was done. Then, RV free wall longitudinal strain(RVFWLS) was calculated by averaging peak systolic strain values of the three segments of the free wall, global longitudinal strain (GLS) was measured from the average values of peak systolic strain of RV free-wall and septal wall at (a) after 6 months and (b) after 9 months of chemotherapyBack to article page
