Hemodynamic data from endotoxemic and control animals

Treatment	Heart rate (beats per minute)	Systolic pressure (mm Hg)	Ejection fraction (percentage)	(dP/dT)/EDV	Emax
LPS	392 ± 152	108 ± 8	38 ± 2	44 ± 3	2.5 ± 0.4
Controla	313 ± 30	112 ± 6	52 ± 8	121 ± 11	7.7 ± 0.6
	P = NS	P = NS	P < 0.05	P < 0.05	P < 0.05

^aSaline-treated rats. dP, derivative of pressure; dT, derivative of time; EDV, end diastolic volume; E_max, maximal end-systolic elastance; LPS, lipopolysaccharide-treated rats; NS, not significant.
