目的：分析急性冠状动脉综合征心电图表现及与冠状动脉造影结果相关性。方法：选择2010年1月至2013年6月收治的急性冠状动脉综合征患者120例,所有患者均做心电图和冠状动脉造影检查,观察其心电图表现,分析心电图表现与冠状动脉造影结果的相关性。结果：①STEMI 心电图表现为相应导联ST段抬高/弓背向上抬高,T波高耸、双相、倒置多变,多合并心律失常；NSTEMI心电图表现为肢体导联、胸导联ST段压低,T波低平、倒置,ST-T改变持续存在和ST-T呈动态衍变两种情况；UA心电图表现形式多样,以发病时ST-T缺血性改变为主；②STEMI、NSTEMI患者病态狭窄血管发生率为100%,明显高于UA患者的31.43%,比较差异有统计学意义(χ2=4.63,P<0.05)；③ACS心电图分型与血管狭窄程度相关性分析,ACS心电图分型与血管狭窄程度有关联(χ2=5.68,ν=8,P<0.05),Pearson列联系数rp=0.570。结论：ACS心电图表现具有多样性,STEMI、NSTEMI患者发生单支或多支冠状动脉血管狭窄程度>50%的概率较高,ACS心电图分型与血管狭窄程度有相关性。%Objective:To study the correlation of ECG and coronary angiography of acute coronary ar-tery syndrome. Method:120 cases of acute coronary syndrome from Jan. 2010 to Jun. 2013 in our hospital, all patients had electrocardiogram and coronary angiography, observed the ECG and its correlation with coro-nary angiography. Result:①ECG manifestations of STEMI was corresponding ST segment elevation in lead /arched elevation, T wave height, duplex, inverted and changeable and mostly complicated with arrhythmia;ECG manifestations of NSTEMI was limb lead, precordial ST segment depression, T wave flat, inversion, ST-T were persistence and ST-T dynamically evolve; The manifestations’ forms of UA was diversity, mostly was the ischemic change of ST-T;②The occurrence rate of morbid stenosis in patients with STEMI, NSTE-MI was 100%, significantly higher than 31. 43% of UA patients, the difference was statistically significant (χ2=4.63,P<0.05);③According the correlation analysis of the ACS electrocardiogram degree and vascular stenosis, the ACS electrocardiogram degree was associated with vascular stenosis (χ2=5.68,ν=8,P<0.05) , Pearson contingency coefficient rp=0.570. Conclusion:The electrocardiogram manifestations of ACS has di-versity, STEMI, NSTEMI patients have a higher probability of more than 50% of single or multi vessel coro-nary artery stenosis, ECG classification of ACS is correlated with the degree of vascular stenosis.
