摘　　要：目的对心电图对不稳定型心绞痛血管病变的定位诊断及与冠状动脉造影的符合程度进行分析,从而更加明确心电图诊断的准确度。方法采用回顾分析的方法 ,选取40例确诊为不稳定型心绞痛的患者,对40例患者心电图检查的情况与冠状动脉造影结果进行分析,观察血管病变的情况。结果正常心电图13例,其中冠状动脉造影单支血管病变6例(4例轻度狭窄,2例中度狭窄),多支血管病变7例(6例中度狭窄,1例重度狭窄);不正常心电图27例,其中冠状动脉造影单支血管病变4例(1例轻度狭窄,3例中度狭窄),多支血管病变23例[23例均为重度狭窄(5例单支堵塞)]。结论心电图是诊断不稳定型心绞痛血管病变的常用方法 ,但如果部分患者的心电图表现不明显,则容易造成误诊,必要时应行冠状动脉造影检查。Objective To analyze coincidence between localization diagnosis of unstable angina pectoris vasculopathy by electrocardiogram and coronary arteriography, and to pinpoint accuracy of diagnosis by electrocardiogram. Methods A retrospective analysis was made on 40 patients with diagnosed unstable angina pectoris. Electrocardiogram and coronary arteriography outcomes in 40 patients were analyzed to observe vasculopathy. Results There were 13 cases with normal electrocardiogram, including 6 cases with single- vessel lesion shown by coronary arteriography （4 mild stenosis cases and 2 moderate stenosis cases） and 7 cases with muhiple-vessel lesion （6 moderate stenosis cases and 1 severe stenosis case）, and 27 cases with abnormal electrocardiogram, including 4 cases with ingle-vessel lesion shown by coronary arteriography （1 mild stenosis case and 3 moderate stenosis cases） and 23 cases with multiple-vessel lesion [ 23 severe stenosis cases （5 cases with single block） ] . Conclusion As a common method in diagnosing unstable angina pectoris vasculopathy, electrocardiogram may lead to misdiagnosis due to inconspicuous manifestation, and coronary arteriography is necessary for certain condition.
