Abstrakt		Reperfusion in acute myocardial infarction (AMI) is accompanied by various ventricular arrhythmias. Therefore, the dynamics of late potentials (LP's) in "reperfused" patients is of interest. High amplification, filtered and averaged surface ECG's as well as 24-hour ECG's were recorded in 58 patients with AMI, treated with a brief intravenous infusion of streptokinase. LP'S were determined within the first 6 hours of infusion and 5 to 10 days later. Results obtained from a group with presumed reperfusion (early creatine kinase activity peak and disappearance of pain, appearance of "specific" arrhythmias) were compared to those obtained from patients with no reperfusion. The first recording showed significantly higher incidence of LP's in the group with reperfusion (p less th. 0.005). In the time between the 2 recordings, the incidence of LP's decreased in significantly higher proportion in the same group (p less th. 0.0002). There was no significant correlation between LP's and radionuclide-determined left ventricular ejection fraction, location of AMI and infarct size index. Conslusion: reperfusion arrhythmias of high degree occur together with "reperfusion LP's". However, it seems that LP's appear more frequently than complex ventricular arrhythmias in AMI patients with reperfusion due to thrombolytic therapy.
