ABSTRACT
An early repolarization variant (ERV) in inferolateral leads has recently been associated with vulnerability to ventricular fibrillation. These studies have been conducted in the occidental countries. The prevalence of ERV in the population of the Maghreb is unknown. The aim of this study was to evaluate the prevalence and risk factors of ERV in a young population from Algeria. METHODS: We assessed the prevalence of ERV within a population of 441 healthy subjects (mean age 25 years) using 12-lead electrocardiography. ERV was stratified by three independent cardiologists according to the J-point elevation (≥0.1mV) in the inferior, apicolateral or both leads with QRS slurring or notching. RESULTS: The inferolateral ERV pattern was present in 55 subjects (12.4%). A malign ERV (>2mm) was present in 5 subjects (9% of ER) and ER in inferior and lateral leads in 40% of ER. An ERV pattern was more frequently associated with young age, male, bradycardia and T wave in V1 lead. CONCLUSION: An ERV is a common finding in a healthy Algerian young population. This prevalence seems to be more important than other studies due to young age and not to a racial difference. Our population were more at risk that other studies, and we found more T waves in V1 lead in this people, due to an ethnic particularities or a phenotypic association with the Brugada syndrome.

This article reports an acute ischemic stroke after cardioversion and atrial flutter catheter ablation in a patient on treatment by dabigatran 110mg twice daily. Trans-esophageal echocardiography did not show any thrombi. Even if this event cannot be attributed to the treatment, this article indicates that prospective studies are necessary.
