[The action of noradrenaline on cardiac energetics in the rat].
Noradrenaline induced a parallel shift of the energy expenditure regression with no statistically significant change of the regression coefficient in isolated rat heart. It also increased the energy expenditure when acting upon and arrested heart with the energy exchange level approximating a non-contractile energy expenditure in the working heart preparation. This finding seems to be mainly due to changes in the non-contractile energy exchange.
