Spatial T Wave Changes Produced by Exercise in Health and Disease
スポンサーリンク
概要
- 論文の詳細を見る
This study was undertaken to analyze the spatial change in T waves that occurred during exercise in patients with ischemic heart disease and hypertension, and to evaluate the clinical significance of these changes in terms of the ventricular gradient.(1) The exercise vector at 15 sec. in normal and mild hypertensive patients did not change the direction, but decreased its magnitude. This fact is as same as the ventricular gradient is decreased its magnitude and does not change its direction in changing heart rate in normal person. This suggested that the T wave change at 15 sec. was influenced mainly by a change in heart rate.(2) The exercise vector at 15 sec. in cases with myocardial infarction, arteriosclerotic heart disease and severe hypertension was directed to the area with evidence of myocardial infarction and enlargement, which suggests that a local ventricular gradient vector influenced the T wave changes at 15 sec.(3) The exercise vector 15 sec. after beginning exercise was thought to be diagnostically useful in determining ischemic areas of the heart.
