Figure 3From: Left ventricular torsion shear angle volume analysis in patients with hypertension: a global approach for LV diastolic functionClassification of HTN by E/A ratio and by torsion hysteresis area. Cutoff values are defined as control’s mean-1SD for E/A ratio and control’s mean + 1SD for THA. Solid black line, cutoff value for E/A ratio; dash black line, cutoff value for THA; THA, torsion hysteresis area.Back to article page
