isoprenaline did not produce any alpha-adrenergic effect , and so purely beta-adrenergic vasodilatation and thus reduced secondary stress on the heart , accompanied by beta-adrenergic cardiac stimulation , eventually brought about an altered circulatory situation which was , basically , comparable to circulation under conditions of physical stress , in cases of physical stress , particular attention should be given to polyfactorially caused cardiovascular transformation , contrary to the beta-adrenergic stimulation by isoprenaline .
