Fig. 1From: Comparison of echocardiographic indices of right ventricular systolic function and ejection fraction obtained with continuous thermodilution in critically ill patientsCorrelation matrix of transthoracic echocardiography parameters of right ventricular systolic function parameters and right ventricular ejection fraction. RVEF, right ventricular ejection fraction; TAPSE, tricuspid annular plane systolic excursion; S′, peak systolic velocity of pulsed tissue Doppler at tricuspid annulus; IVA, isovolumic acceleration; EDDr, end-diastolic diameter ratio; RIMP, right ventricular index of myocardial performance; FAC, fractional area change. Spearman’s correlations are computed amongst all variables. Positive correlations are represented by red squares and negative correlations by blue squares. Larger squares and darker colors represent higher correlation coefficient. ***p < 0.001, **p < 0.01, *p < 0.05Back to article page
