【摘要】 目的探讨心电图、心电向量图、多普勒彩色超声心动图对心肌梗死不同阶段的诊断价值。方法收集90例经心脏肌钙蛋白定性试验和动态心电图演变确诊的62例急性心肌梗死患者和28例陈旧心肌梗死患者为研究对象,对心电图、心电向量图、超声心动图在心肌梗死不同阶段诊断的敏感性进行比较。结果心电图检出急性心肌梗死41例(66.13%),较心电向量图19例(30.65%)和超声心动图2例(3.23%)明显升高,差异有统计学意义(χ2=56.176,P<0.001);陈旧心肌梗死组28例,心电向量图检出陈旧心肌梗死15例(53.57%),较心电图6例(21.43%)和超声心动图7例(25.0%)明显升高,差异有统计学意义(χ2=7.821,P=0.02);心电图与超声心动图呈正相关(r=0.78,P=0.031);超声心动图直观地检出2例左心室室壁瘤。结论心电图在心肌梗死急性期价值较高;心电向量图在陈旧性心肌梗死的诊断指标多于心电图;室壁瘤形成后超声心动图较心电图和心电向量图的诊断更有价值。更多还原

【Abstract】 Objective To investigate the application value of electrocardiogram and vectrocardiography and dopler ultrasonic cardiography in diagnostic of myocardial infarction different stages.Metholds 90 patients with myocardial infarction were divided into two groups in which acute myocardial infarction group 62 cases(68.89%) patients and old myocardial infarction group 28 cases(31.11%) patients.Ananisys positive rates and compared its sensitivity between acute myocardial infarction group and old myocardial infarction group in myocardial infarction.Results It has statistically significant(χ~2=56.176,P<0.001) that electrocardiogram detected 41 cases with acute myocardial infarction(66.13%) higher than vectrocardiography 19 patients(30.65%) and dopler ultrasonic cardiography 2 cases(3.23%).Old myocardial infarction group 28 cases,vectrocardiography application value show significant differences(χ~2=7.821,P=0.02)in old myocardial infarction group 15 cases(53.57%) compared with electrocardiogram group 6 patients(21.43%) and dopler ultrasonic cardiography group 7 cases(25.0%).Electrocardiogram group and vectrocardiography group correlation coefficient(r=0.78,P=0.031) shows statistically significant.Dopler ultrasonic cardiography intuitively detected 2 cases ventricular aneurysm.Conclusion Electrocardiogram can better reflect acute myocardial infarction than others,Vectrocardiography diagram in old myocardial infarction indicator than electrocardiogram,However dopler ultrasonic cardiography as a intuitionistic imaging method to diagnosis ventricular aneurysm after myocardial infarction varied significantly than electrocardiogram or vectrocardiography.更多还原
