Benign early repolarization (BER):

Question

Quizplus · Accepted Answer

BER produces an infarct-like pattern on the ECGs of healthy, asymptomatic patients. BER is considered a normal ECG variant that does not imply, or exclude, coronary artery disease. BER produces ST elevation, which, in this case, is most often seen in the chest leads. In general, maximal ST elevation in BER is seen in leads V₂ to V₅. Additionally, BER produces tall, symmetric T waves resembling those seen in the hyperacute phase of myocardial infarction. This combination creates a pattern on the ECG that closely resembles that of anterior or anterolateral infarction. J-point elevation in BER is usually accompanied by a slur, oscillation, or notch at the end of the QRS just before and including the J-point. Just as with pericarditis, a notch at the J-point causes one to consider noninfarct conditions as possible explanations for the ST-segment elevation. In general, R-wave and T-wave voltages are large in BER.BER is a normal and benign finding. It is more common in men than in women, particularly in young healthy men between 20 and 40 years of age. BER has the highest prevalence in athletic African American men younger than 40 years.
