[Effect of the new anti-arrhythmia preparation Bonnecor on the hemodynamics and activity of the ischemic heart].

The effect of newly-developed anti-arrhythmia drug Bonnecor compared to that of ethacizin and lidocaine has been studied on anesthetized rats under acute myocardial ischemia. The drugs injected intravenously prior to coronary artery occlusion have been shown to prevent to a great degree the appearance of hemodynamic and functional disturbances of the heart. When compared to control, less reduction in systemic arterial pressure, systolic discharge cardiac output, contractility and heart power were observed. In addition, Bonnecor has been found to have certain advantages over reference drugs.
