Right bundle branch block and coved-type ST-segment elevation mimicked by acute cholecystitis.

A 69-year-old woman had acute cholecystitis that mimicked right bundle branch block with coved-type ST-segment elevation in the precordial electrocardiogram leads (Brugada-type ST shift). The patient did not have obvious heart disease, syncope, or a family history of sudden death. The coved-type ST-segment elevation disappeared as the acute inflammation subsided. Intravenous administration of pilsicainide, a pure sodium channel blocker, could reproduce the Brugada-type ST shift. This is the first report of the Brugada-type ST shift occurring in association with acute cholecystitis.
