WHAT’S KNOWN?
Frontal QRS-T angle, which is a novel marker of the heterogeneity in myocardial depolarization and repolarization, is described as the absolute difference between myocardial depolarization (QRS- axis) and repolarization (T axis). It can easily be measured by using the 12-lead surface electrocardiography (ECG).The frontal QRS-T angle has been shown to be valuable in predicting many cardiac and non-cardiac diseases.
