[Effect of sympathetic nerve stimulation on myocardial reactive hyperemia]

It has been established in experiments on 25 dogs that the peak of reactive hyperemia (RH) of the myocardium cannot be regarded as an absolute criterion of the coronary dilatory reserves. Stimulation of the stellate ganglion under the conditions of arterial blood pressure stabilization increased the peak of RH. After-effect of the sympathetic nerve stimulation also led to a rise in the peak of RH as compared with control.
