AbstractThe 12-lead surface electrocardiogram adjacent QTc dispersion, which is the maximum difference of corrected QT interval between two adjacent leads, is a simple method to determine regional variation in repolarization and refractoriness. The aim of this study is to evaluate adjacent QTc dispersion as a marker of susceptibility to ventricular arrhythmias after myocardial infarction. A total of 135 consecutive patients with acute myocardial infarction were enrolled in the study. Adjacent QTc, measured by lens magnifier, was calculated on the first, second and third days after acute myocardial infarction. On the second day after acute myocardial infarction, adjacent QTc dispersion was significantly greater in patients with ventricular arrhythmias (P < 0.001). Adjacent QTc dispersion on the first and fifth day after acute myocardial infarction was not associated with development of ventricular arrhythmias. On the second day after acute myocardial infarction, adjacent QTc dispersion is a simple and feasible method for prediction of ventricular arrhythmias.
