[Effect of small doses of pituitrin on electrocardiography of ischemia in the experiment].

A new type of reaction to the myocardial ischemia was established in chronic experiments in conscious dogs. It consists in some changes of local myocardial activity and, consequently, in constant or transient normalization of ECG. Pharmacological stabilization of this process augments myocardial resistance to ischemia 40-50 times and more. The role of small doses of pituitrin in this reaction was established.
