[Correlation of a change in the amplitude of the R wave during ergometry with the finding of significant stenosis of the coronary artery].
The authors evaluated retrospectively 224 patients with ischaemic heart disease. These patients were subjected to an ergometric loading test on a bicycle ergometer followed by angiography of the coronary arteries. With regard to the site of the increased amplitude of R waves during the loading test the patients were divided into seven groups which were sub-divided further according to the coronarographic finding. The authors investigated the assumption that patients with pathological changes of R waves above the anterior wall suffer from afflictions of the ramus interventricularis anterior, patients with changes above the lateral wall of the ramus circuflexus and patients with increased R waves above the inferior wall of the right coronary artery. From the work ensues that no localization of increased amplitudes of R waves during the loading test has a statistically significant correlation with the coronarographic finding.
