Comparison between control group and PAH patients regarding 2D strain measurements of RV free wall segments: basal, mid and apical. a LpsS; b LpsSR. LpsS, longitudinal peak systolic strain; LpsSR, longitudinal peak systolic strain rate; PAH, pulmonary arterial hypertension; RV, right ventricle; * PAH vs control group, p < 0.05
