Hypothesis-generating for ectotherm cardiac thermoregulation; extends comparative physiology but leaves open mammalian translation.
In the green iguana, increased oxygen consumption at higher temperatures is driven by increased heart rate and AV difference, despite a decrease in stroke volume, suggesting a thermoregulatory bypass mechanism.
Vance A. Tucker (1966) studied this question.
