Repolarization Characteristics in Early Repolarization and Brugada Syndromes: Insight into an Overlapping Mechanism of Lethal Arrhythmias

摘要

Repolarization Indices in ER and Brugada Syndromes. Introduction: We reported impaired QT-rate dependence in early repolarization syndrome (ERS); however, contemporary data have shown peak incidence of sudden cardiac death (SCD) in ERS and Brugada syndrome (BrS) at mid-night and early morning. Taken together, we analyzed the nocturnal QT-rate dependence in both syndromes.
