title: [Incidence of painless ischemic heart disease].
abstract: A 24-hour ECG monitoring was carried out in 130 patients with stable exercise angina pectoris and history of myocardial infarction. A diagnosis of ischemic heart disease was based on anamnesis, positive result of exercise test and dipyridamole test, and the result of coronary angiography in some patients. Patients with unchanged repolarization period in ECG were classified to the study. Electrocardiogram was registered with Holter technique in patients performing their usual activities. Recorded ECG was analysed with visual technique in Medilog 3000 system. Two hundred thirty seven ischemic episodes were shown in the examined patients, including 69% of painless ischemic attacks and 31% of ischemic attacks with anginal pain. Duration of painless ischemic attacks with anginal pain. Duration of painless ischemic attacks was longer, heart rate slower, and ST segment elevation did not differ in both types of myocardial ischemia.
