EARLY REPOLARIZATION SYNDROME: ELECTROCARDIOGRAPHIC SIGNS AND CLINICAL IMPLICATIONS


Authors: Ciprian Rezus, Valentin Ambăruț, Nicoleta Dima, Simona Daniela Ionescu, Mariana Floria




 

Introduction: Early repolarization syndrome (ER) was previously considered a benign variant, but in recent years has emerged as a marker of risk for idiopathic ventricular fibrillation and sudden death.

 

Methods and results: In particular, ER in the inferior ECG leads has been associated with idiopathic ventricular fibrillation and has been termed as the ER syndrome (ERS). It is mainly seen in young men, athletes and blacks. The elevation of the J point and/or ST segment from the baseline by at least 0.1 mV, in at least two adjoining leads, was considered as ER signs. Electrocardiographic territory, degree of J-point elevation and ST-segment morphology are associated with different degrees of risk for subsequent ventricular arrhythmia. Several clinical entities cause ST segment elevation. Clinical and ECG data are most important for differential diagnosis.

 

Conclusion: At present the dataset is insufficient to allow risk stratification in asymptomatic individuals.
