Early Repolarization

Mon, 06/29/2015 - 15:55 -- Dawn

This ECG was obtained from a healthy 29-year-old man.  It shows "benign early repolarization".    It demonstrates the typical pattern of widespread ST elevation with a normal concave upward sloped ST segment.  There are also prominent U waves in V2 through V4, and T wave inversions in the inferior wall leads. He was not complaining of any symptoms and, in fact, donated this ECG as an example of known early repolarization pattern.  The other changes may represent normal variations for his age and gender. Early repolarization has long been thought to be a completely benign variant, and it is quite common in young people, especially athletic men.  But new research suggests a possible link to future serious arrhythmias. For a discussion of research on this topic from the Journal of the American College of Cardiology, see this link.  Research reported in the New England Journal of Medicine can be accessed at this link.
