[Upward displacement of the ST segment of an exercise electrocardiogram. Correlation with coronarography].
7 cases with upward displacement of the R-ST segment in the course of effort were compared with the data derived from the coronary arteriography. The lesions were found to be severe in 4 cases, mildly significant or not at all so, in 3 cases. The sub-epicardial lesion on effort, as Prinzmetal's angina, does not make it possible to foresee the degree of the responsible stenosis, which may vary through a superadded spasm, and encourage to undertake an aorta-to-coronary artery by-pass.
