Echocardiography parameters for WT ± IH
| RA (n = 8) | Hypoxia (n = 7) | P | |
|---|---|---|---|
| HR, beats/min | 510.2 ± 23.5 | 493.4 ± 21.6 | 0.61 |
| LVEDD, mm | 3.04 ± 0.13 | 3.26 ± 0.14 | 0.27 |
| LVESD, mm | 1.47 ± 0.12 | 1.63 ± 0.07 | 0.26 |
| RWT | 0.51 ± 0.03 | 0.49 ± 0.03 | 0.61 |
| LV Mass, mg | 68.12 ± 5.53 | 79.43 ± 5.91 | 0.19 |
| FS, % | 52.10 ± 2.46 | 49.86 ± 0.95 | 0.42 |
| EF, % | 76.63 ± 2.36 | 74.81 ± 0.96 | 0.49 |
Values are means ± SE. Heart rate (HR), left ventricle end diastolic (LVEDD) and systolic (LVESD) diameters, relative wall thickness (RWT), calculated left ventricle (LV) mass, fractional shortening (FS), and ejection fraction (EF) are all calculated from echocardiography measurements. See materials and methods for calculations. Measures for the two groups are compared with unpaired, two-tail t-tests; P values are listed.
