Fig. 2. Routine cardiac performance before, during and after the anoxic period as a
function of time. Representative measurements were taken; (1) before
maxtest1; (2) 0, 5, 10, 15 and 20 min into the anoxic test; and 3)
before maxtest2. (A) Input pressure was adjusted in an attempt to
maintain flow at 12, 16, 20 or 24 ml min-1 kg-1 for 5,
10, 15 and 18°C hearts (see text for further explanation). (B) Power
output. (C) Heart rate. (D) Stroke volume. (E) Cardiac output. Letters
indicate significant changes within each group during anoxia relative to
values at the onset of anoxia: bdifferences for hypoxic hearts at
5°C, chypoxic hearts at 10°C, dhypoxic hearts at
15°C and ehypoxic hearts at 18°C.
