[Use of transesophageal electrostimulation of the atrium and nitroglycerin test in the evaluation of the degree of risk of the development of cardiac complications after reconstructive surgery in patients with Leriche's syndrome].

Abstract By the method of transesophageal electrostimulation of the left auricle, 98 patients with Leriche's syndrome were examined. Of them in 51, the coronary disease was revealed. The degree of ischemic changes in the terminal part of the ventricular complex were defined by the rate of stimulation, depth of the ST segment shift, and duration of ischemic depression. The nitroglycerin test permitted to evaluate the anti-ischemic effect of the drug, quality and effectiveness of the preoperative preparation. In patients with negative or doubtful anti-ischemic effect, the risk of the development of cardiac complications increases.
