Forty-nine patients with coronary atherosclerosis (according to the results of selective angiography), whose ages ranged from 29 to 59 years, were examined. Comparison with the results of ECG at rest and the findings of coronarography showed no changes in the QRS complex in 16% of patients with lesions of two and in 10% of those with obstructive changes in three main coronary artery. Displacement of the ST segment as a sign of myocardial ischemia during physical exercise tests in leads V5--V6 of the ECG coincided with obstructive lesions of the left coronary artery in 91% of cases. Patients suffering from obstructive lesions of the right coronary artery with or without atherosclerotic changes in the left coronary artery reacted by depression of the ST segment in the II, III, and aVF leads of the ECS. The authors suggest that there exists a mechanism of "intracoronary steal" of perfusion blood supply when the ischemic changes on the ECG do not coincide with the localization of coronary atherosclerosis.
对49例年龄在29至59岁之间、患有冠状动脉粥样硬化（根据选择性血管造影结果）的患者进行了检查。将静息心电图结果与冠状动脉造影结果进行比较发现，在两支血管病变的患者中，16% 的患者QRS波群无变化；在三支主要冠状动脉出现阻塞性改变的患者中，10% 的患者QRS波群无变化。在心电图V5 - V6导联进行体力运动试验时，ST段移位作为心肌缺血的征象，91% 的病例与左冠状动脉阻塞性病变相符。患有右冠状动脉阻塞性病变且左冠状动脉有或无动脉粥样硬化改变的患者，心电图II、III和aVF导联出现ST段压低。作者认为，当心电图上的缺血改变与冠状动脉粥样硬化的定位不一致时，存在一种“冠状动脉内盗血”的灌注血液供应机制。
