ST-T wave changes in a patient complicated with vasospastic angina and Brugada syndrome: differential responses to acetylcholine in right and left coronary artery

Mitsuhiro Nishizaki et al. Heart Vessels. 2008 May.

Abstract

A 49-year-old man with chest pain and syncope presented saddleback or occasionally coved type ST elevation in V1-V3. Coronary spasm in the left anterior descending artery was induced by acetylcholine injection and ST elevation changed from saddleback to coved type in V2-V3 together with ST depression in V4-V5, whereas acetylcholine injection into the right coronary artery did not provoke spasm, but induced augmented and coved type ST elevation in V2 without ST-T changes in V4-V5. These electrocardiographic changes in response to acetylcholine administration into each coronary artery are compatible with pathogenesis of vasospastic angina and Brugada syndrome, respectively.
