[Holter monitoring of ECG and exercise tests in patients with ischemic heart disease on the stage of preparation for surgical revascularization of the myocardium].
One hundred and fifty-two patients aged from 30 to 82 years were examined. All the patients were divided into 3 groups: group 1 -- patients with macrofocal scar alteration of the myocardium, group 2 -- patients with small-focus scar alteration of the ardium, group 3 -- patients without myocardial infarction. Increase of the number of patients with disturbances of cardiac rhythm of high gradations was seen in all groups of patients during exercise test and after-exercise period. These disturbances were first diagnosed in 15,6% patients of group 1, in 14% patients of group 2 and in 22% patients of group 3. It is concluded that exercise tests must be performed very carefully in patients with low tolerance to exercise. If there is combination of several risk factors, it is recommended to refuse exercise tests.
