Spatial indices of repolarization correlate with non-ST elevation myocardial ischemia in patients with chest pain

Background: Mild-to-moderate ischemia does not generally result in ST segment elevation on the ECG, but rather it frequently results in non-specific, dynamic changes in the T wave. These repolarization changes are frequently considered non-diagnostic for ischemia, warranting further diagnostics that are costly and time-consuming. Robust methods to quantify such T wave heterogeneity can have immediate clinical applications. We sought to evaluate the effects of spontaneous ischemia on the evolution of spatial T wave changes in patients undergoing nuclear cardiac imaging for evaluating intermittent chest pain.
