Baseline hemodynamics derived from PV analysis in control and shunt lambs

	Control	Shunt	P Value
EDV, ml	22.8 ± 5.9	48.7 ± 10.0	0.01*
ESV, ml	14.4 ± 1.4	33.5 ± 9.8	0.04*
SV, ml	8.7 ± 1.8	15.8 ± 2.7	0.04*
CI, ml·min−1·kg BW−1	73.9 ± 4.0	159.2 ± 25.1	0.04*
HR, beats/min	131.8 ± 3.7	129.0 ± 10.7	0.81
Ees	2.3 ± 0.44	1.16 ± 0.32	0.02*
PVA, mJ	0.026 ± 0.0079	0.063 ± 0.013	0.03*
Efficiency, %	89.6 ± 5.6	80.2 ± 7.7	0.18

Values are expressed as mean of means ± SE of mean; n =6 in each group.

EDV, end-diastolic volume; ESV, end-systolic volume; SV, stroke volume; CI, cardiac index; BW, body weight; Ees, end elastance (slope of end-systolic pressure-volume relationship); HR, heart rate; PVA, pressure volume area.

Efficiency = stroke work/PVA.
