[Assessment of early arrhythmias in acute experimental myocardial infarct in rabbits].
Arrhythmias were studied at the early stage after rapid ligation of the left ventricular artery on an experimental model of arrhythmia in rabbits. The rabbits were subjected to thoractomy and ligation of the left ventricular artery under direct visualization. The electrocardiographic and hemodynamic parameters were recorded. Electrocardiographic signs of infarction and changes in rhythm were recorded in 60% of the animals. The rate of cardiac contractions and the arterial pressure decreased after the ligation. In the group in which practolol was applied the rate of arrhythmias dropped to 25%. The effect of adrenergic beta-block on acute occlusion of the coronary artery is discussed.
