Comparison of the results of provocation electrocardiographic tests with the questionnaire for detection of exertion-induced stenocardia (data of the epidemiological study)

The results of a combination of functional electrocardiographic tests were compared with those of a WHO questionnaire for angina of effort. Coronary disease was verified in 37% of patients with a double diagnosis of angina of effort, and in 100% of cases of angina of effort combined with ischemic electrocardiographic changes.
