[Significance of the atrial stimulation test in the diagnosis of ischemic heart disease. A comparison with measured physical loading on the bicycle ergometer and with coronary angiographic data].

The results of the atrial stimulation test were compared with the data of the test on a bicycle ergometer and coronary arteriography. The atrial stimulation test made it possible to diagnose coronary insufficiency in 91.6% of patients with ischemic heart disease. It was established that atrial stimulation helps in determining exactly the causes of a vague cardialgic syndrome in some cases in which the test on a bicycle ergometer cannot be carried out or when it is difficult to appraise its results. As compared to the test with dosed physical load on a bicycle ergometer, the atrial stimulation test proved more sensitive and less specific.
