title: [Characteristics of the anti-arrhythmia effect of phosphocreatine in the acute stage of experimental myocardial infarction].
abstract: Antiarrhythmic and antifibrillatory effects of exogenous phosphocreatine, administered to animals at different dates after the onset of experimental myocardial infarction, were examined. Experiments were carried out on anesthetized dogs with acute one-step coronary artery ligation or in waking dogs 24 to 48 hours after two-step ligation of the descending branch of the left coronary artery (Harris's method). Major cardiac functional and hemodynamic parameters and ECG were recorded. The values obtained, using these models, show that exogenous phosphocreatine possesses high antiarrhythmic and antifibrillatory activities within first hours of coronary occlusion and is less effective after 24 hours of infarction.
