[Possibilities of Surface ECG Mapping in Diagnosis of Ischemic Heart Disease in Patients With Aortic Stenosis]
Method of surface ECG mapping and graded bicycle exercise test were used for noninvasive detection of coronary artery involvement in 24 patients with aortic stenosis. The actual presence of coronary artery disease was verified by coronary angiography. Isointegral ST-segment maps were constructed and analyzed. Stepwise discriminant analysis revealed parameters of maps most significant for diagnosis of ischemic heart disease. Two discriminant equations based on these parameters allowed to detect noninvasively coronary artery involvement in patients with aortic stenosis.
