[Value of 24-hour ECG Holter monitoring in the evaluation of painless episodes of ST segment depression in patients with ischemic heart disease].
The paper presents the results of examination of 149 patients with ischemic heart disease. All the patients underwent 24-hour Holter monitoring; selective coronary angiography according to M. Judkins was performed in 142 patients, 29 patients were subjected to a bicycle ergometric test adopted in the All-Union Cardiology Research Center, USSR Academy of Medical Sciences. In the patients with ischemic heart disease, features and rates for detecting the painless episodes of ST-segment depression from the data of 24-hour Holter monitoring. Painless episodes of ST-segment depression were revealed in 82% patients with sclerosing atherosclerosis of the coronary bed. These were most frequently found in patients with three diseased vessels in the coronary bed or impaired left coronary trunk. Painful episodes of ST-segment depression were more pronounced and prolonged in the majority of patients.
