What is Chapman's sign?

S Serge Barold. J Electrocardiol. 2024 Nov-Dec.

Abstract

Chapman's (electrographic) sign is of a notch on the ascending limb of the R wave in leads I, aVL and V6. It has been used in the diagnosis of myocardial infarction (MI) during left bundle branch block (LBBB) and cardiac pacing. A number of studies have yielded divergent results about its diagnostic usefulness. However, the sign can be helpful in the diagnosis of MI during LBBB or pacing in the absence of other manifestations of MI.

Keywords: Cardiac pacing; Chapman's sign; Electrocardiography; Left bundle branch block; Myocardial infarction.
