Diagnostic and prognostic value of the QRS-T-angle, an ECG marker quantifying heterogeneity of depolarization and repolarization, in patients with suspected non-ST-elevation myocardial infarction

Background: The value of the 12-lead ECG in the diagnosis of non-ST-elevation myocardial infarction (NSTEMI) is limited due to insufficient sensitivity and specificity of standard markers of ischemia and because ECG confounders may prevent their application. The QRS-T-angle reflects depolarization –repolarization heterogeneity and might assist in diagnosis and prognosis of patients with suspected NSTEMI.
