Slopes of ventilatory efficiency (VE/VCO2) to partial pressure of arterial oxygen (PaCO2) at peak exercise are compared in patients with HVS and controls. The shift of the slope of this relationship in patients with HVS is consistent with the observed higher VD/VT ratio (i.e. higher ventilation-perfusion mismatch).</p
