title: Various 12-lead electrocardiographic findings of diffuse three-vessel coronary artery spasm.
abstract: Electrocardiographic signs of diffuse three-vessel coronary artery spasm may show various findings including no ST segment changes, according to whether or not a difference of an electrical gradient develops between the anterior and inferior regions because of global ischemia. This study suggests that diffuse three-vessel coronary artery spasm must be considered when the 12-lead electrocardiogram (ECG) shows no important ST segment changes with episodes of angina and diffuse coronary artery spasm during an ergonovine provocation test in patients with strongly suspected variant angina.
