Echocardiographic measurements of left ventricular ejection fraction, fractional shortening and wall motion score index.

<p>All values are the mean ± SD (n = 5–6).</p>*<p>p<0.05 vs. the control group;</p>#<p>p<0.05 vs. the baseline value. BL: baseline; H30 min: end of hypovolemia; T120 min: end of lactic acid infusion; T180 min: end of fluid infusion; and T300 min: end of the experiment.
