Abstract
The oxygen consumption (QO2) of non-stimulated trabecula carneae from the rat was determined at various resting tensions. It was found that the aerobic metabolism of this heart muscle preparation was uninfluenced by resting tensions comparable to those in vivo. The QO2 of the trabecular muscle was not increased when the trabecula were stimulated once per second and allowed to contract isotonically.Keywords
