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.

查普曼的星座是什么？

查普曼（电图）征是指在 I、aVL 和 V6 导联的 R 波上升沿上出现一个切迹。它被用于诊断左束支传导阻滞（LBBB）和心脏起搏时的心肌梗死（MI）。许多研究对该征象的诊断作用得出了不同的结果。不过，在没有其他心肌梗死表现的情况下，该征象有助于诊断左束支传导阻滞或心脏起搏时的心肌梗死。
