Fig. 1From: Association of left ventricular longitudinal strain with central venous oxygen saturation and serum lactate in patients with early severe sepsis and septic shockScatterplots of (a) left ventricular ejection fraction (EF) and central venous oxygen saturation (ScvO2), (b) longitudinal strain and ScvO2, (c) EF and lactate, and (d) strain and lactate. These graphs illustrate that elevated lactate and low ScvO2 may be observed with elevated EF but are less often observed with normal strainBack to article page
