title: [Differential diagnosis of ischemic heart disease and cardialgia by means of pharmacological tests in the polyclinical practice].
abstract: The possibility of differential diagnosis of ischemic heart disease and cardialgia at a polyclinic is analyzed. A total of 1110 patients with a preliminary diagnosis of ischemic heart disease were examined. In 214 of them the data gathered during many years of observations have cast doubt on the validity of this diagnosis. The patients of this group were made to undergo tests with potassium chloride and obsidan. Subject to appraisal were the ECG reaction and an analysis of angular variations of the vectors in the terminal portion of the ventricular complex. The described tests were shown to help determine the significance of "functional" or "organic" changes of the myocardium in the genesis of repolarizational ECG perturbances.
