[Clinical characteristics, immediate therapeutic results and the outcome in rhythm and conductivity disturbances in myocardial infarct].

Certain rhythm and conduction disorders in 252 patients with myocardial infarction were studied. Twenty one of them had auricular fibrillation, influenced by medicaments, with the exception of one, six had relapses and 4 of the patients died. Ventricular extrasystoles (frequent, polytopic, more than three one after the other, R of T) were found in 48 patients. Regardless of the reported good result from the treatment of ventricular extrasystoles, ventricular tachycardia originated in 10 and ventricular fibrillation--in 9 patients. Ventricular fibrillation (a total of 29 patients) was more frequent in patients with cardiac insufficiency (25%) as compared with those (6.1%). With the combination of cardiac insufficiency and ventricular extrasystole, a very high risk group is formed--every third patient develops ventricular fibrillation. Four patient out of 22 patients, were discharged with timely initiated treatment of the ventricular fibrillation. Complete atrioventricular block was recorded in 12 of the patients with a lethality of 50%. Conclusions are drawn as regards the duration of prophylaxis and treatment of rhythm and conduction disorders and in-patient days of the patients in the intensive care unit.
