title: Early repolarization: innocent or dangerous?
abstract: Electrocardiographic (ECG) findings of wide QRS complexes in right precordial leads with saddle ST elevation in patients with polyarthritis, palpitations and family history of syncope urged us to review early repolarization syndrome (ERS). ERS is commonly seen in young men. The main ECG features are as follows: wide spread concave ST-segment elevation, more in the precordial leads (usually V2-V4); notching or irregular contour of J point and prominent concordant T waves with large amplitude. ERS was historically considered as a benign ECG variant. In recent years, it has emerged as a marker for increased risk of sudden cardiac death. The purpose of this review was to describe the ECG manifestations of this syndrome and to review the literature concerning its arrhythmogenic potential. The authors found it important not only discussing the rate of ERS life threatening but also to reemphasize its differences from other syndromes. Some of the last are much more dangerous: acute myocardial infarction and Brugada syndrome. The tables will be helpful for physicians to distinguish ERS from other syndromes in patients with chest pain and ST elevation.
