title: Diffuse triple-vessel coronary artery spasm complicated by idioventricular rhythm and syncope.
abstract: A 70-year-old man presented with diffuse triple-vessel coronary arterial spasm accompanied by ST segment elevation in the inferior and anterior leads when the severity of pain moderated. At the beginning, he noted throat and chest pain followed by syncope. Atropine, norepinephrine, and lidocaine were administered therapeutically. The initial electrocardiogram showed an idioventricular rhythm without ST segment deviations, which made the prompt diagnosis of coronary arterial spasm difficult.
