[The effect of metabolic agents on the antiarrhythmic activity of novocainamide and acetylnovocainamide].

The effects of potassium malate and sodium succinate on the antiarrhythmic activity of novocainamide and acetylnovocainamide during modelling of chlor-calcium-induced arrhythmia as well as in disorders of cardiac rhythm during modelling of pituitrin-isadrine-induced myocardial infarction were studied. The metabolic agents were found to increase the effectiveness of acetylnovocainamide and the toxicity of novocainamide. To interpret the specific features of the mechanism of the anti-arrhythmic action of the compounds there was studied their ability to form complexes with components of biomembranes and ions of biometals.
