Effect of prenatal hypoxia on functional indexes of guinea pig offspring. Guinea pig offspring were exposed to prenatal normoxia (NMX) or hypoxia (HPX, 10.5% O₂ for 14 days) and raised in a normoxic environment until 90 days of age. Functional indexes of stroke volume, cardiac output, ejection fraction, and fractional shortening of left ventricular diameter (LVD) were measured using pulse-wave Doppler ultrasound. Values are means ± SE; n = 9 NMX and 9 HPX males and 9 NMX and 9 HPX females. *P < 0.05 vs. NMX.
