目的探讨体表心电图对老年人冠心病的诊断价值。方法将105例老年人体表心电图与冠状动脉造影进行对比分析。结果105例患者中心电图阳性81例,其中冠状动脉造影阳性65例,冠状动脉造影阴性16例;心电图阴性24例,其中冠状动脉造影阳性14例(包括4例肌桥),冠状动脉造影阴性10例。在不同的年龄组中,男性患者冠状动脉造影阳性率高于心电图阳性率,但差异不显著(p>0.05);女性患者中,85岁以上年龄组造影与心电图阳性率一致,而65～74岁及75～84岁组冠状动脉造影阳性率均低于心电图阳性率,差异不显著(p>0.05)。随着冠状动脉病变支数的增加,心电图诊断冠心病的阳性率也越高。结论体表心电图作为临床诊断老年人冠心病具有简单、快捷、经济、易于接受等优点,是老年人重要的无创性检查方法之一。
Objective To investigate the diagnostic value of surface electrocardiogram (ECG) on coronary heart disease in the elderly. Methods 105 cases of elderly body surface electrocardiogram and coronary angiography comparative analysis. Results The electrocardiogram of 81 patients was positive in 105 patients, of which 65 were positive coronary angiography and 16 negative were coronary angiography; 24 were negative electrocardiogram, of which 14 were positive coronary angiography (including 4 cases of muscle bridge), 10 were negative coronary angiography example. In different age groups, the positive rate of coronary angiography in male patients was higher than the positive rate of ECG, but the difference was not significant (p> 0.05). In female patients, the positive rate of electrocardiogram was consistent with the age group of 85 years old, The positive rates of coronary angiography in the age group of 75-84 years old were lower than that of the electrocardiogram positive group, the difference was not significant (p> 0.05). With the increase of coronary lesion count, the positive rate of ECG diagnosis of coronary heart disease is also higher. Conclusion Body surface electrocardiogram is one of the most important noninvasive methods for senile patients as its clinical diagnosis of coronary heart disease in the elderly is simple, rapid, economical and easy to accept.
