[Drug prevention of cardiac rhythm disorders during the acute period of myocardial infarct].

Among 152 patients with myocardial infarction admitted to a specialized department within a few hours (1st day) of the onset of the disease without cardiac rhythm disorders, or with "minor" arrhythmias, 31 patients were receiving Panangine intravenously, 10--20 ml daily, for 7 days since the moment of admission. Another group of patients was comprised of 75 persons who, in addition to the above regimen of Panangine therapy, received at the moment of their admission a single intramuscular injection of Retabolil (50 mg). The control group was formed by 46 patients receiving no antiarrhythmic drugs. Monitoring of the cardiac rhythm during the acute period of myocardial infarction demonstrated that with preventive employment of Panangine prognostically dangerous rhythm disorders (especially paroxysmal tachycardia) developed less often than in the controls. A combined employment of Panangine and Retabolil resulted in a still better preventive effect, largely preventing, among other developments, the appearance of multiple polytopic extrasystoles. No ventricular fibrillation was observed in the examined patients.
