title: Exercise stress body surface isopotential map in patients with coronary artery disease: comparison with coronary angiographic and stress myocardial perfusion scintigraphic findings.
abstract: to locate the ischemic area in 22 patients with angina pectoris, exercise stress body surface isopotential maps (MAPs) were assessed and compared with coronary angiography and myocardial stress scintigraphy. Taking coronary angiographic findings into consideration, 4 types of ischemic MAP responses, i.e., septum and anterior, lateral, inferior, and posterior wall ischemia were postulated. Sensitivity of stress MAP was 71% for the average and more than stress imaging. Specificity of stress MAP was 46% for the average and less than stress imaging.
