Early repolarization pattern (ERP) is a common electrocardiographic (ECG) variant, characterized by J point elevation manifested either as QRS slurring (at the transition from the QRS segment to the ST segment) or notching (a positive deflection inscribed on terminal S wave), ST-segment elevation with upper concavity and prominent T waves in at least two contiguous leads.1,2 The prevalence of ERP in normal population varies from 1 % to 13%, depending on the age (predominant in young adults), the race (highest amongst black population), and the criterion for J point elevation (0.05 mV vs. 0.1 mV).3-7 In addition, higher incidence of ERP exists in males, athletes and individuals with high vagal tone or selective loss of sympathetic tone (e.g. spinal cord injury).8
