early repolarisation syndrome
Definition An EKG-defined condition characterised by an elevation of the J point and/or ST segment from the baseline by ≥ 0.1 mV in at least 2 adjoining leads. Early repolarisation detected by inferior EKG leads is associated with idiopathic ventricular fibrillation (VF), is known as ERS, and is seen mainly in young men, athletes, and blacks.
Once regarded as benign, early repolarisation is now regarded as a risk factor for idiopathic VF and sudden death.
Synonym Normal variant RS-T segment elevation
