An increase in QT dispersion (QTd) is associated with myocardial ischemia and may serve as a marker of ischemia and ventricular arrhythmia. We studied the effect of early reperfusion with rheolytic thrombectomy using an angiojet catheter (Possis, Minneapolis, MN) on QTd in 12 patients who presented with acute myocardial infarction. QTd and QT dispersion, rate-corrected for RR interval, were significantly reduced from 57 ± 16 and 68 ± 13 msec before reperfusion to 34 ± 16 and 44 ± 19 msec after reperfusion respectively (mean ± SD; P < 0.002 and P < 0.0008, respectively). Successful reperfusion with rheolytic thrombectomy reduces QTd and may confer electrical stability to vulnerable myocardium. Reduction in indexes of repolarization inhomogeneity with reperfusion may serve as a noninvasive marker of coronary patency.
