Area of Science:

• Cardiology
• Electrophysiology
• Medical Diagnostics

Background:

• J-wave syndromes, including Brugada syndrome (BrS) and early repolarization syndrome (ERS), present diagnostic challenges.
• Existing diagnostic criteria require updates to reflect emerging knowledge and consensus reports.
• Standardization in terminology and measurement is crucial for accurate diagnosis and patient management.

Purpose of the Study:

• To review and present the revised diagnostic criteria for Brugada syndrome (BrS) and early repolarization syndrome (ERS).
• To clarify terminology, diagnostic standards, and differential diagnosis for J-wave syndromes.
• To compare and contrast the features of BrS and ERS.

Main Methods:

• Systematic review of the "J-Wave Syndromes Expert Consensus Conference Report: Emerging Concepts and Gaps in Knowledge" (2016).
• Integration of information from "The Early Repolarization Pattern" (2015) consensus paper for ERS.
• Comparative analysis of diagnostic criteria, modulating factors, and phenotypical presentations.

Main Results:

• Outlines updated terminology and diagnostic criteria for BrS and ERS.
• Discusses modulating factors, acquired Brugada pattern, and Brugada phenocopies.
• Highlights similarities and differences between BrS and ERS.

Conclusions:

• Revised diagnostic criteria enhance the understanding and management of J-wave syndromes.
• Standardized terminology and differential diagnosis improve clinical practice for BrS and ERS.
• Further research is needed to address knowledge gaps in J-wave syndromes.
