The changes in the basic hemdynamic indices and in the phase structure of the cardiac cycle in patients with acute infarction prior to and post treatment with beta-blockers (Obsidan and Trasicor) were studied. Manifested changes in the hemodynamics were established, namly: pulse rate and cardiac flow decrease, the total peripheral resistance grows; veloqcilty of blood flow is slowed down. The preparations used have a negative effect upon the phase structure of left ventricle as well. The authors underline that beta-blockers administration in acute myocardial infarction should be evaluated very carefully and in the presence of clinical signs for cardiac insufficiency, it should be carried out on the background of cardiotonic treatment.
