[JT interval changes in acute myocardial infarction following coronary angioplasty].
OBJECTIVE
The aim of the study was to determine the influence of early reperfusion on the behavior of JT interval in patients with acute myocardial infarction undergoing percutaneous transluminal coronary angioplasty.


METHODS
Coronary angiography and percutaneous transluminal coronary angioplasty were done for 14 acute myocardial infarction patients. Measurements were performed from 12-lead surface electrocardiogram with "Kaunas-Load" equipment before percutaneous transluminal coronary angioplasty, 5 minutes and 24 hours after it.


RESULTS
Immediately after percutaneous transluminal coronary angioplasty there were shortenings of JT and JT dispersion (JTd) and after 24 hours in all the patients prolongation of JT and JTd intervals was observed.


CONCLUSIONS
Changes of the repolarization during percutaneous transluminal coronary angioplasty could be related with ischemic myocardial lesion. Early reperfusion has positive impact on the ventricular repolarization.
