[Measured physical load test and the atrial stimulation test in the differential diagnosis of ischemic heart disease in patients with unchanged coronary angiograms].

Assessment of the clinical findings and the results of the bicycle ergometry test conducted in 17 patients and the atrial stimulation test performed in 13 patients allowed the diagnosis of ischemic heart disease to be made in 8 of 20 patients with normal coronary arteriogram. It is noted that the combined performance of the test with dosed physical load on a bicycle ergometer and the atrial stimulation test raises their values in differential diagnosis. The authors content that to improve the differential diagnosis of ischemic heart disease and functional cardiopathy in patients with normal coronary arteriogram it is advisable to study coronary microcirculation and myocardial metabolism during performance of the atrial stimulation test.
