Objective: The purpose of this study was to investigate the relation between electrical dispersion and impairment of ventricular filling in patients with acute myocardial infarction (MI). Methods: Thirty patients with recent myocardial infarction (17 patients with anterior and 13 patients with inferior MI) were included in the study. QT dispersion (QTd) was defined as maximum minus minimum QT interval durations. Flow propagation velocity measured by color m-mode echocardiography was used to determine diastolic function. Results: There was a positive correlation between isovolumic relaxation time and QTd, as well as negative correlation existed between left ventricular flow propagation velocity (LVFPV) and QTd. The QTd was greater and LVFPV was lower in patients with anterior myocardial infarction as compared with those with inferior MI. Conclusion: There is an association between electrical dispersion and left ventricular filling abnormalities in patients with acute myocardial infarction.
