AbstractEarly repolarization pattern (ERP), a form of J-wave syndromes, was considered long time a benign ECG phenomenon. However, recent data confirmed that certain phenotypes of ERP are related to an increased risk of sudden cardiac death (idiopathic ventricular fibrillation). Our paper gives a short and practical update regarding the main issues related to ERP: epidemiological data, molecular and electrophysiological background, clinical significance and risk stratification. At the end, the future directions of research and clinical management related to ERP are presented.

The review article is devoted to the diagnosis and clinical significance of early ventricular repolarization phenomenon and syndrome. Just 13 years ago, the phenomenon was recognized as an unambiguous version of the norm. However, the results of a series of multicenter studies have shown that the phenomenon is associated with an increased risk of sudden cardiac death. The following criteria are recognized as criteria for early repolarization: the presence of a notch or a junction wave on the descending part of the R wave with a concomitant (or absent) elevation of the ST segment (at the Jt point); J wave (point) ≥0.1mV peak elevation (at Jp point) in ≥2 adjacent 12-channel ECG leads, except for V1–3 leads; QRS duration, measured in leads with J wave (point) <120 ms. Early repolarization syndrome is a clinical condition involving a combination of the pattern of early repolarization and polymorphic ventricular tachycardia, ventricular fibrillation and/or sudden cardiac death in persons without structural heart disease. Treatment is required in patients with a symptom of ventricular tacharrhythmia or family history early repolarization with sudden cardiac death.

Early Repolarization Syndrome

Malignant early repolarization as cause of sudden death has taken on great importance in recent years. It has been described as an entity capable of producing ventricular arrhythmic events, causing from episodes of syncope to sudden cardiac death. Ventricular fibrillation is the typical arrhythmia in these patients, with no clear relationship to date with idiopathic monomorphic ventricular tachycardia. Electrocardiographic markers related to the development of arrhythmic events in early repolarization syndrome have been described. They seem not only related to the development of ventricular fibrillation, but also to sustained monomorphic ventricular tachycardia, as is the case described in the article.
