title: [Diagnostic potential of the first ECG derivative in assessing the coronary artery status of patients with ischemic heart disease].
abstract: The results of the maximal rate of heart ventricle activation (HVA) determined according to the ECG readings and its first derivative were compared in 38 patients suffering from coronary disease (CD) with the coronarography data. 54 healthy men without the clinical and bicycle ergometry signs of CD were examined as control. In patients with angina pectoris, postinfarction cardiosclerosis and acute myocardial infarction, there was a significant decrease of HVA. As the rate of the degree of coronary artery stenosis increased, there was a progressive reduction of the rate of HVA.
