TL;DR: The J-wave syndromes (JWSs) consisting of the Brugada syndrome (BrS) and early repolarization syndrome (ERS) have captured the interest of the cardiology community over the past 2 decades following the identification of BrS as a new clinical entity.

TL;DR: The study results indicate that mutations in the LTCCs are detected in a high percentage of probands with J-wave syndromes associated with inherited cardiac arrhythmias, suggesting that genetic screening of Ca(v) genes may be a valuable diagnostic tool in identifying individuals at risk.

TL;DR: To the Editor: Early repolarization, consisting of an elevation of the QRS–ST junction (J point), QRS notching or slurring (J wave), and a tall, symmetric T wave, is generally considered to be benign.

TL;DR: This study identified SCN10A as a major susceptibility gene for BrS, thus greatly enhancing the ability to genotype and risk stratify probands and family members.

TL;DR: This study provides additional evidence in support of the hypothesis that ER pattern in the ECG is not always benign and transient augmentation of global J waves may be indicative of a highly arrhythmogenic substrate heralding multiple episodes of VF in patients with ER pattern.
