Abstract
Transesophageal pacing (TEP) was performed in 54 patients with atheroscrelotic vascular disease to detect ischemic heart disease (IHD). Thirty patients had arteriosclerosis obliterans of the lower extremities (ASO) and 24 patients aortic aneurysm (AA). All patients underwent coronary arteriography. Sensitivity for the diagnosis of IHD was 90% and the specificity 67%, accuracy 83% in ASO and sensitivity 80%, specificity 93%, accuracy 88% in AA. In both vascular diseases the sensitivity was 87%, the specificity was 83%, and the accuracy was 85%. These results suggest that TEP is a useful screening test to detect IHD in patients with atheroscrelotic vascular disease who are candidates for surgery.
