Extreme example of early repolarization

Once accepted as a benign phenomenon, electrocardiographic early repolarization pattern is now considered to have significant clinical importance. Haïssaguerre et al. (1) were first to describe the possible association between early repolarization pattern and idiopathic ventricular fibrillation. Since then, numerous studies have documented the clinical association between early repolarization pattern and future arrhythmic events. Due to different definitions, the prevalence of early repolarization pattern varies widely between 2% and 31% (2). The 2015 European Society of Cardiology Guidelines for the management of ventricular arrhythmias and the prevention of sudden cardiac death recommend that early repolarization syndrome (ERS) should be diagnosed only in patients with early repolarization pattern on electrocardiography (ECG) and a history of resuscitated cardiac arrest or a documented episode of ventricular fibrillation and/or polymorphic ventricular tachycardia (3). Also, due to lack of clear evidence, the panel experts could not make recommendations for the management
