摘　　要：目的探讨心电图(ECG)联合心电向量(VCG)对冠心病心肌缺血的诊断价值。方法选取正常体检者10例、无症状冠心病心肌缺血患者18例、有症状冠心病心肌缺血患者39例作为研究对象,均进行心电图和心电向量检查。比较正常体检者、无症状冠心病心肌缺血患者、有症状冠心病心肌缺血患者额面和横面T向量环情况,T环方位、运转及三面ST向量情况;比较心电图单独检测与心电图联合心电向量检测冠心病心肌缺血的阳性率。结果有症状冠心病心肌缺血患者和无症状冠心病心肌缺血患者额面和横面T环电压、L/W、T/R、T-QRS夹角比较差异无统计学意义(P>0.05);正常体检者额面和横面T环电压、L/W、T/R明显高于无症状冠心病心肌缺血患者和有症状冠心病心肌缺血患者,T-QRS夹角明显小于无症状冠心病心肌缺血患者和有症状冠心病心肌缺血患者,差异具有统计学意义(P<0.05)。正常体检者T环转向、T环顺时钟运行及三面ST向量≥0.1 mV占比均低于无症状冠心病心肌缺血患者和有症状冠心病心肌缺血患者,差异具有统计学意义(P<0.05)。无症状冠心病心肌缺血患者心电图联合心电向量检测冠心病心肌缺血阳性率94.44%明显高于心电图单独检测的66.67%;有症状冠心病心肌缺血患者心电图联合心电向量检测冠心病心肌缺血阳性率97.44%明显高于心电图的76.92%,差异具有统计学意义(P<0.05)。结论应用心电图联合心电向量检测可有效提高冠心病心肌缺血的临床检出率,可为临床治疗提供参考依据,具有较高的诊断价值。Objective To discuss the diagnostic value of electrocardiogram(ECG)combined with vectorcardiogram(VCG)in myocardial ischemia of coronary heart disease.Methods 10 normal subjects,18 patients with asymptomatic myocardial ischemia of coronary heart disease and 39 patients with symptomatic myocardial ischemia of coronary heart disease were selected as the research subjects,all of whom underwent electrocardiogram and vectorcardiogram examination.Comparison was made on the frontal and transverse T-vector loops,T-loop orientation,operation and three-sided ST vectors in normal subjects,patients with asymptomatic myocardial ischemia of coronary artery disease,and patients with symptomatic coronary artery disease,and the positive rate of electrocardiogram alone versus electrocardiogram combined with vectorcardiogram for detecting myocardial ischemia of coronary artery disease.Results There was no statistically significant difference in frontal and transverse T-loop voltage,L/W,T/R,and T-QRS angle between patients with symptomatic myocardial ischemia of coronary heart disease and patients with asymptomatic myocardial ischemia of coronary heart disease(P>0.05).The frontal and transverse T-loop voltages,L/W,and T/R in normal subjects were significantly higher than those in patients with asymptomatic myocardial ischemia of coronary heart disease and patients with symptomatic myocardial ischemia of coronary heart disease,and the T-QRS angle was significantly smaller than that of patients with asymptomatic coronary heart disease and patients with symptomatic myocardial ischemia of coronary heart disease.All the differences were statistically significant(P<0.05).The percentages of T-loop steering,T-loop clockwise running and three-sided ST vectors≥0.1 mV were lower in normal subjects than in patients with asymptomatic myocardial ischemia of coronary artery disease and patients with symptomatic myocardial ischemia of coronary artery disease,and the differences were statistically significant(P<0.05).In patients with asymptomatic
