Assessment of RV (Top Panel) and LV (Bottom Panel) contractile reserve. Scatter plots depicting rest and peak changes in ejection fraction and stroke volume for RV (EF p = 0.001, SV p = 0.08) and LV (EF p < 0.001, SV p = 0.02). Each line is representative of an individual patient. Dark red line indicates mean value. RV = right ventricle, LV = left ventricle, EF = ejection fraction, SV = stroke volume
