The long QT syndrome (LQTS), classified as congenital or acquired, is a multi-factorial
disorder of myocardial repolarization predisposing to life-threatening ventricular …

Chronic heart failure is a clinical syndrome with multiple etiologies, associated with
significant morbidity and mortality. Cardiac arrhythmias, including ventricular …

Ambulatory ECG (AECG) is very commonly employed in a variety of clinical contexts to
detect cardiac arrhythmias and/or arrhythmia patterns which are not readily obtained from …

Objectives: The purpose of this study was to provide a meta-analysis to estimate the
performance of 12 commonly reported risk stratification tests as predictors of arrhythmic …

Background—Therapies for patients with chronic heart failure caused by left ventricular
systolic dysfunction have advanced substantially over recent decades. The cumulative effect …

Nonsustained ventricular tachycardia (NSVT) has been recorded in a wide range of
conditions, from apparently healthy individuals to patients with significant heart disease. In …

The high incidence of sudden cardiac death in heart failure (HF) reflects electrophysiologic
changes in response to myocardial failure. We previously showed that short-term variability …

Many studies showed electrocardiogram (ECG) parameters are useful for predicting fatal
ventricular arrhythmias (VAs). However, the studies have several shortcomings. Firstly, all …

Ventricular repolarization is a complex electrical phenomenon which represents a crucial
stage in electrical cardiac activity. It is expressed on the surface electrocardiogram by the …

Aims To identify key structural and electrophysiological features explaining distinct
electrocardiogram (ECG) phenotypes in hypertrophic cardiomyopathy (HCM). Methods and …
