[Comparative evaluation of the importance of transesophageal electrical stimulation of the left atrium and bicycle ergometry in diagnosing ischemic heart disease].
Comparisons were made between the clinical picture, results of bicycle ergometry and selective coronaroangiography, and the data of transesophageal electrical stimulation of the left atrium in 52 patients, including 31 with stenosing coronary atherosclerosis. The feasibility of applying the transesophageal stimulation for the diagnosis of coronary heart disease is shown. The sensitivity of transesophageal electrical stimulation of the left atrium in detecting stenosing coronary atherosclerosis was 81%, its specificity being 79%.
