Frontal QRS-T angle predicts coronary atherosclerotic burden in patients with ST segment elevation myocardial infarction

Abstract

Background: Frontal QRS-T (fQRST) angle is an electrocardiogram (ECG)-derived marker, indicating the concordance between ventricle depolarization and repolarization. A wide fQRST angle has been found to be associated with cardiovascular mortality. The aut
