目的:观察心电描记术联合彩色多普勒超声在心肌梗死心肌瘢痕中的诊断价值。方法:对心肌梗死患者不同治疗方式下开通冠状动脉循环,于发病后4周、8周应用同步十二导联心电图观察fQRS,联合彩色多普勒超声观察LVEF,对心肌梗死患者心肌瘢痕及心脏功能进行对比研究。结果:本组患者发病后4周、8周fQRS阳性导联数,随梗死相关冠状动脉的有效开通而减少,心脏功能改善,组间比较差异有统计学意义(P<0.05),fQRS加LVEF对心肌瘢痕组织的敏感性、特异性、阴性预测值明显提高。结论:心电描记术联合彩色多普勒超声在心肌梗死心肌瘢痕中的诊断价值在组间结果中得到充分肯定,“罪犯”血管开通越早,抗栓治疗越充分,心肌微循环结构和功能损害越轻,则心肌瘢痕越局限,fQRS阳性比率越低,LVEF提高,以急诊PCI组最理想。
Objective: To observe the diagnostic value of electrocardiography combined with color Doppler ultrasound in myocardial scar of myocardial infarction. Methods: The coronary circulation was opened under different treatment in patients with myocardial infarction. FQRS was detected by synchronous 12-lead electrocardiogram at 4 weeks and 8 weeks after onset. Combined with color Doppler ultrasonography, LVEF was observed to detect myocardial scar and heart in patients with myocardial infarction Function comparison study. Results: The number of fQRS-positive leads at 4 weeks and 8 weeks after onset in this group decreased with the effective opening of infarct-related coronary arteries and the heart function improved. There was a significant difference between the two groups (P <0.05). The fQRS plus LVEF Myocardial scar tissue sensitivity, specificity, negative predictive value increased significantly. Conclusion: The diagnostic value of electrocardiography combined with color Doppler ultrasound in the myocardial scar of myocardial infarction is fully affirmed in the inter-group results. The earlier the criminals are opened, the more adequate the antithrombotic therapy, and the myocardial microcirculation structure And functional damage lighter, the more limited myocardial scar, fQRS-positive rate is lower, LVEF increased to the best emergency PCI group.
