The effects of 2,5-di-tert-butylhydroquinone (TBQ) on cardiac muscle contractility were investigated using cardiac preparations from the right ventricle of the rat. In saponin-skinned preparations, TBQ (50 and 100 microM) did not significantly affect the maximal isometric Ca2+-activated force or the
