心电图联合超声心动图对急性肺栓塞的诊断价值

Diagnostic value of electrocardiogram and echocardiography in acute pulmonary embolism

目的探讨心电图联合超声心动图对急性肺栓塞的检出率。方法将43例急性肺栓塞患者作为研究对象,均接受心电图、超声心动图以及心电图联合超声心动图检查,以肺动脉造影为诊断金标准,对比不同方式的检出率。结果心电图的检出率为69.77%(30/43),超声心动图检出率为62.79%(27/43),心电图联合超声心动图的检出率为95.35%(41/43),三组比较,P<0.05,且联合组高于其它两组。结论心电图联合超声心动图对急性肺栓塞的检出率较高,适合临床推广应用。

Objective To explore the diagnostic value of electrocardiogram and echocardiography in acute pulmonary embolism.Methods A total of 43 patients with acute pulmonary embolism were selected.They were all examined by electrocardiogram and echocardiogram.Pulmonary angiography was used as the diagnostic gold standard to compare the detection rate of different methods.Results The detection rate of electrocardiogram was 69.77%(30/43)and that of echocardiography was 62.79%(27/43).The detection rate of electrocardiogram combined with echocardiography was 95.35%(41/43).There was significant difference in detection rate among them.The detection rate of electrocardiogram combined with echocardiography was higher than that of electrocardiogram and echocardiography alone.Conclusion Electrocardiogram combined with echocardiography has high detection rate for acute pulmonary embolism,which is suitable for clinical application.
