An agreed definition of early repolarization was established, requiring the peak of an end-QRS notch and/or the onset of an end-QRS slur (Jp) ≥0.1 mV, without requiring ST-segment elevation.
The term early repolarization has been in use for more than 50 years. This electrocardiographic pattern was considered benign until 2008, when it was linked to sudden cardiac arrest due to idiopathic ventricular fibrillation. Much confusion over the definition of early repolarization followed. Thus, the objective of this paper was to prepare an agreed definition to facilitate future research in this area. The different definitions of the early repolarization pattern were reviewed to delineate the electrocardiographic measures to be used when defining this pattern. An agreed definition has been established, which requires the peak of an end-QRS notch and/or the onset of an end-QRS slur as a measure, denoted Jp, to be determined when an interpretation of early repolarization is being considered. One condition for early repolarization to be present is Jp ≥0.1 mV, while ST-segment elevation is not a required criterion.
“This statement, drafted by leading experts in the field of electrocardiology, provides an insightful review of the state of the art and state of confusion in the field, with thoughtful recommendations for standardization of terminology regarding the early repolarization pattern.”
Macfarlane et al. (Wed,) conducted a review in Early repolarization pattern. Agreed definition of early repolarization was evaluated. An agreed definition of early repolarization was established, requiring the peak of an end-QRS notch and/or the onset of an end-QRS slur (Jp) ≥0.1 mV, without requiring ST-segment elevation.
