[Dynamics of QT interval dispersion in patients with ischemic heart disease during stress test as possible reflection of changes of terminal part of the T-wave].
Changes of QT and QTa interval dispersion during stress test on treadmill and possible dependence of these changes on results of stress test and severity of coronary atherosclerosis were studied in 82 patients with effort angina. All patients were subjected to stress test on treadmill and selective coronary angiography. Before and immediately after stress test duration and dispersion of intervals QT, QTa, QTc and QTac were measured. Basing on obtained results a conclusion was made that changes of QT interval in patients with ischemic heart disease after stress test could be caused by changes of terminal part of T-wave.
