ECG Disease Patterns

Early Repolarisation Syndrome



  • Early repolarisation syndrome (ERS) refers to the presence of J point elevation on an ECG. 
  • Early repolarisation syndrome is also known as benign early repolarisation (BER) and was previously considered a normal variant, however the condition is associated with an increased risk of ventricular arrhythmias and sudden cardiac death.
    • ECG Findings in Early Repolarisation Syndrome

    • ST elevation at the J point (the terminal portion of the QRS complex)
    • J-point notching - a positive deflection directly after the QRS complex
  • The ST elevation of ERS is concave and is different in morphology to the ST elevation that occurs with acute myocardial infarction.
