Primary electrical heart diseases, often considered channelopathies, are inherited genetic
abnormalities of cardiomyocyte electrical behavior carrying the risk of malignant arrhythmias …

Repolarization heterogeneity (RH) is an intrinsic property of ventricular myocardium and the
reason for T-wave formation on electrocardiogram (ECG). Exceeding the physiologically …

Inherited arrhythmia syndromes are a common cause of apparently unexplained cardiac
arrest or sudden cardiac death. These include long QT syndrome and Brugada syndrome …

Electrical storm (ES) is a state of electrical instability, manifesting as recurrent ventricular
arrhythmias (VAs) over a short period of time (three or more episodes of sustained VA within …

Inherited arrhythmia (IA) is one of the main causes of sudden cardiac death (SCD) in young
people, and is reported to be a more prevalent cause of SCD in Asia than in Western …

Background: NS5806 activates the transient outward potassium current I to, and has been
claimed to reproduce Brugada Syndrome (BrS) in ventricular wedge preparations. I to …

Nademanee et al reported the efficacy of the arrhythmogenic substrate ablation for Brugada
syndrome. 1 The substrate was defined as abnormal late fractionated electrograms recorded …

Background An increase in local dispersion of repolarization (DOR) may contribute more to
arrhythmogenesis as compared to changes of global DOR. The aim of this simulation study …

Early repolarization pattern (ERP) has traditionally been regarded as benign and is often
encountered in apparently healthy individuals. In the absence of organic heart disease and …

Previous reports suggested there are 2 phenotypes of ERS: one with a late depolarization
abnormality predominantly in the right ventricular epicardium, and the other with pure ERS …
