Abstract: QT dispersion has been recognized as an undesirable marker because of its association with arrhythmogenicity in patients with myocardial infarction, but the relation between QT interval dispersion and wall motion abnormalities has not been clarified. After the introduction of reperfusion therapy, it was recognized that T waves were inverted twice in the course of myocardial infarction. An investigation was made of the clinical significance of QT dispersion in relation to the presence of inverted T waves and left ventricular wall motion abnormalities in 34 patients (mean age, 59 years) with acute anterior myocardial infarction who underwent successful reperfusion therapy. The ...
