title: [Electrocardiographic loading tests in persons with various ECG changes (findings of epidemiological studies)].
abstract: The results from a complex of functional electrocardiographic tests (exercise test, transesophageal pacing of the left atrium, dipyridamole test and cold test) were compared with resting ECG data by using epidemiological findings from a study conducted in Novosibirsk. In the absence of other signs of the disease, coronary heart disease was verified in 11.1% of the persons with prominent Q-QS waves, in 10.0% of those with small Q-QS, in 16% of those with slightly altered ST segment and T wave, in 35.3% with marked altered ST-T interval, and in 50% of those with marked altered ST-T interval in the presence of left ventricular hypertrophy. The total number of cases with coronary heart disease amounted to 20.8% in the presence of ischemic ECG changes.
