The study was conducted in 55 patients with cardiac pains. Electrocardiography was used successively prior to, during and following physical exercises, followed by Seldinger selective coronary angiography, and electrocardiography prior to, during and following hyperventilation tests. In 2 of 55 patients the result of the exercise test was interpreted as false-positive, since the coronary angiography demonstrated intact vessels, and during hyperventilation ECG recorded a decreased ST segment. To avoid false-positive results in patients with suspected angina pectoris the physical exercises tests can be considered positive only in cases in which hyperventilation caused no ECG changes typical for angina pectoris.
该研究对55例有心脏疼痛的患者进行。在体育锻炼前、锻炼期间和锻炼后依次进行心电图检查，随后进行Seldinger选择性冠状动脉造影，并在过度通气试验前、试验期间和试验后进行心电图检查。55例患者中有2例运动试验结果被判定为假阳性，因为冠状动脉造影显示血管完好，且过度通气期间心电图记录到ST段下降。为避免疑似心绞痛患者出现假阳性结果，只有在过度通气未引起心绞痛典型心电图变化的情况下，体育锻炼试验才能被视为阳性。
