The recommendations listed in this clinical practice guideline are, whenever possible,
evidence-based. An initial extensive evidence review, which included literature derived from …

Myocardial ischemia is a pathophysiological state characterized by inadequate perfusion of
the myocardium, resulting in an imbalance between myocardial oxygen demand and supply …

Instabilities in ventricular repolarization have been documented to be tightly linked to
arrhythmia vulnerability. Translation of the information contained in the repolarization phase …

Increases in beat-to-beat variability of electrocardiographic QT interval duration have
repeatedly been associated with increased risk of cardiovascular events and complications …

Microvolt-level T-wave alternans (TWA) assessed by spectral method during an exercise
stress test has been widely studied for risk stratification. Several studies have documented …

The purpose of this study was to investigate the beat-to-beat variability of T-waves (TWV)
and to assess the diagnostic capabilities of T-wave-based features for myocardial infarction …

QT interval variability, mostly expressed by QT variability index (QTVi), has repeatedly been
used in risk diagnostics. Physiologic correlates of QT variability expressions have been little …

Background: T-wave alternans (TWA) is defined as a consistent variation in the
repolarization morphology that repeats on every other beat. This study aimed to evaluate …
