title: [Clinical evaluation of 2 new methods of non-invasive diagnosis of coronary insufficiency].
abstract: One-dimensional hyperplane was determined as capable of distinguishing between patients with coronary insufficiency and normal subjects by some parameters of bicycle ergometry. Twenty-four normal subjects and 159 anginal patients (males with normal blood pressure and normal body weight) were tested by bicycle ergometry. Test results were assessed individually with respect to changes in electrocardiographic repolarization complex, changes in R-wave amplitude, Robinson's index and the index of myocardial adaptation to exercise. All examined tests showed similar specificity. The myocardial adaptation index had significantly higher sensitivity as compared to other three indices.
