METHOD FOR DIAGNOSING LATENT CORONARY VASOSPASM IN PATIENTS POSSESSING MYOCARDIAL ISCHEMIA

摘要

FIELD: medicine. SUBSTANCE: method involves performing transesophageal electric cardiostimulation in patients with negative ergometric test by increasing stepwise each minute the heart beat rate by 20 beats per 1 min until the submaximum value of heart beat rate is reached (160 beats per 1 min). Depression or elevation of ST segment on the electrocardiogram by 1 mm or more being observed, latent coronary vasospasm is diagnosed in myocardial ischemia patients. EFFECT: enhanced reliability of diagnosis.
