Interpreting The Sub Xiphoid View (2)
RV/LV ratios in healthy controls in one study revealed a mean of 0.51 (95% confidence interval, 0.48-0.54). Meanwhile those with known pulmonary hypertension had ratios of 1.47 (mean, 95% confidence interval, 1.25-1.70). The RV/LV ratio correlated significantly with pulmonary artery pressure.

The rv/lv ratio correlates with pulmonary artery pressure and the normal should be around 0.5. Ratios above 1 are associated with adverse clinical outcomes
