Introduction Electrocardiographic (ECG) changes in heart failure with reduced, mildly
reduced, and preserved ejection fractions can be critical in clinical assessment while waiting …

Duchenne muscular dystrophy (DMD) is a clinically common X-linked recessive myopathy,
which is caused by mutation of the gene encoding dystrophin on chromosome Xp21. The …

Objectives: This study investigated the rates and predictors of SD or aborted cardiac arrest
(ACA) in HFpEF. Background: Sudden death (SD) may be an important mode of death in …

Background A number of studies have assessed the predictive effect of QRS-T angles in
various populations since the last decade. The objective of this meta-analysis was to …

Abstract Background Frontal QRS-T (fQRST) angle is an electrocardiogram (ECG)-derived
marker, indicating the concordance between ventricle depolarization and repolarization. A …

Background: Electric excitation initiates myocardial mechanical contraction and coordinates
myocardial pumping. We hypothesized that ECG global electric heterogeneity (GEH) and its …

Background Early risk stratification based on SYNTAX score plays a crucial role to identify
the need for early invasive strategy in patients with NSTEMI. The predictive role of frontal …

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 …

The incidence and mechanisms of sudden cardiac death (SCD) among patients with heart
failure with reduced ejection fraction have been well characterized. Conversely, limited data …

Background Recent studies have demonstrated that the frontal QRS-T angle, defined as the
angle between the mean QRS and T vectors, is a strong independent predictor of mortality in …
