Fig. 4From: Systolic time ratio measured by impedance cardiography accurately screens left ventricular diastolic dysfunction in patients with arterial hypertensionDiscriminative ability of PEP, LVET, STR and D wave to identify LVDD in hypertensive patients, as determined by the AUC and ROC curves. STR AUC = 0.97; PEP AUC = 0.81; LVET AUC = 0.82; D Wave AUC = 0.88. AUC, area under the curve; LVDD, left ventricular diastolic dysfunction; LVET, left ventricle ejection time; PEP, pre-ejection period; STR, systolic time ratioBack to article page
