Wj. Brady, BENIGN EARLY REPOLARIZATION - ELECTROCARDIOGRAPHIC MANIFESTATIONS ANDDIFFERENTIATION FROM OTHER ST SEGMENT ELEVATION SYNDROMES, The American journal of emergency medicine, 16(6), 1998, pp. 592-597
Early repolarization, also known as benign early repolarization (BER)
or normal variant, is noted in approximately 1% of the population and
in up to 48% of patients seen in the emergency department with chest p
ain. BER represents a benign variant of the normal electrocardiogram a
nd is one of several syndromes producing electrocardiographic ST segme
nt elevation. BER electrocardiographically includes diffuse or widespr
ead ST segment elevation. upward concavity of the initial portion of t
he ST segment, notching or slurring of the terminal QRS complex, and c
oncordant T waves of large amplitude. This article focuses on BER and
includes a discussion of the electrocardiographic tools useful in maki
ng this diagnosis and in distinguishing BER from other ST segment elev
ation syndromes. (Am J Emerg Med 1998;16:592-597. Copyright (C) 1998 b
