运动平板试验心电图的变化与冠状动脉病变部位的关系探讨

Research on relationship between ECG changes in treadmill exercise test and coronary artery lesion

目的通过探讨运动平板试验心电图的变化与冠状动脉病变部位的关系,为利用运动平板试验检查确定"罪犯"血管提供依据。方法选择石家庄市第一医院心血管内科于2011年01月—2011年12月间242例临床疑为冠心病患者而运动平板试验阳性且在同期(1个月内)行冠状动脉造影的患者,分析结果。结果运动平板试验心电图V1～V3导联、V4～V6导联ST段压低改变预测的罪犯血管主要为左前降支(LAD)。结论运动平板试验心电图ST段改变对冠状动脉病变部位的定位有一定价值。

Objective To explore the relationship between ECG changes in treadmill exercise test and coronary artery lesion,it is aimed at providing evidences for the identification of the ＂culprit vessel＂ by digging further advantage of treadmill exercise test.Methods The selection of 242 patients with both suspected CHD and positive treadmill exercise test as well as the performance of synchronized（within 1 month）coronary angiography during the period from Jan.2011 to Dec.2011 in Department of Cardiovascular Diseases of No.1 Hospital of ShiJiazhuang.Then analyze these informations.Results Leads V1~V3 or V4~V6 with ST segment depression changes in treadmill exercise test can predict that the main culprit vessel is left anterior descending（LAD）.Conclusion ST segment changes in treadmill exercise test is useful to predict coronary artery lesions.
