DOI: 10.1002/joa3.12756
Abstract: It is known that a wide frontal QRS‐T(f[QRS‐T]) angle in the electrocardiography (ECG) is associated with poor cardiovascular outcomes. The Tp‐e (the interval from the peak to the end of the T wave) interval and… read more here.

DOI: 10.1007/s00380-020-01601-4
Abstract: The QRS-T angle has been associated with adverse cardiovascular events and sudden cardiac deaths. We determined frontal QRS-T angle in patients with complete transposition of the great arteries (TGA) after atrial switch operation and repaired… read more here.

DOI: 10.1016/j.jelectrocard.2017.02.008
Abstract: Abnormal orientation of the T-wave axis and increased angle between the QRS complex (depolarization) and the T-wave (repolarization) have long been assumed to provide a global measure of repolarization abnormality, and have been used to… read more here.

DOI: 10.1016/j.jelectrocard.2020.02.001
Abstract: INTRODUCTION Cardiac involvement is a leading cause of morbidity and mortality in primary light chain (AL) amyloidosis. The electrocardiographic spatial QRS-T angle reflects changes in the direction of the repolarization sequence and is a powerful… read more here.

DOI: 10.1016/j.jelectrocard.2022.02.002
Abstract: BACKGROUND Paradoxical ventriculophasic response (P-VR), a rare entity, has not been fully investigated. This study sought to compare the electrocardiographic features of P-VR and typical ventriculophasic response (T-VR). METHODS The 12‑lead electrocardiogram (ECG) data recorded… read more here.

DOI: 10.1016/s0735-1097(17)33407-1
Abstract: Background: Exercise stress electrocardiography (ECG) alone is underutilized despite guideline recommendations in part due to poor diagnostic accuracy. High frequency QRS analysis (HF-QRS) is a novel tool to supplement standard ST-analysis during stress ECG. We… read more here.
