体表心电图对门诊冠心病患者临床诊断及护理分析

目的：研究体表心电图（Electrocardiogram，ECG）对我院门诊冠心病患者诊断的临床诊断价值研究及护理分析。方法：选择2010年1月至2014年1月在我院初步诊断的冠心病患者230例作为研究对象。对患者行常规静息12导联的ECG检查及CAG检查，分析ECG的临床诊断结果、冠脉狭窄程度的诊断结果以及冠脉狭窄支数的诊断结果，并给出相应的护理措施。结果：ECG对于冠心病的诊断灵敏度为77.14%（135/175）。135例CAG阳性患者的冠脉狭窄情况中，中度组的阳性符合率与轻度组相比，差异无统计学意义（P﹥0.05）。重度组的阳性符合率显著高于轻度组，差异有统计学意义（P﹤0.05），但与中度组相比，差异无统计学意义（P﹥0.05）。冠脉狭窄支数为二支的阳性符合率与一支组相比，差异无统计学意义（P﹥0.05）。冠脉狭窄支数为三支的阳性符合率与一支组及二支组相比，差异均无统计学意义（均P﹥0.05）。患者在护理后疼痛症状及焦虑情绪均明显缓解，与护理前相比，差异均有统计学意义（均P﹤0.05）。患者对于护理工作作出的评分中，﹥90分者占84.78%，显著高于﹤60分、60-80分以及80-90分者，差异均有统计学意义（均P﹤0.05）。结论：ECG诊断冠心病有一定价值，但也存在误诊情况，临床上可与其他方案联合检测。同时，给予一定的护理措施较为重要，值得重视。

Clinical Diagnosis and Nursing Analysis of Surface Electrocardiogram on Outpatients with Coronary Heart Disease

Objective：To study clinical diagnostic value and nursing analysis of surface electrocardiogram on outpatients with coronary heart disease in our hospital. Methods：230 patients with tentatively diagnosed coronary heart disease （CHD）from January,2010 to January,2014 in our hospital were chosen as the research object. The patients were checked with routine resting of 12 - lead ECG examination and CAG examination. The clinical diagnostic results of ECG, the degree and number of coronary artery stenosis were analyzed. The corresponding nursing measures were given. Re-sults：The sensitivity of ECG for the diagnosis of coronary heart disease was 77. 14%（135 / 175）. Among the 135 cases of the CAG positive patients of coronary artery stenosis cases,there was no statistical difference（P ﹥ 0. 05）when positive coincidence rate of moderate group were compared with that of mild group. Positive coincidence rate of severe group was significantly higher than that of mild group. The difference was statistically significant（P ﹤ 0. 05）. but when compared with the moderate group,there was no statistically significant difference（P ﹥ 0. 05）. When the positive coincidence rate of biramous coronary stenosis was compared with a ramal group,there was no statistically significant difference（ P ﹥0. 05）. When the positive coincidence rate of three ramal coronary stenosis was compared with one or two ramal group, there was no statistically significant difference（P ﹥ 0. 05）. By nursing pain symptoms and anxiety of patient were evi-dently relieved. Compared to nursing before,the differences were statistically significant（P ﹤ 0. 05）. Among the assess-ment of patients to nursing,the grades that more than 90 points accounted for 84. 78% . This was significantly higher than﹤ 60,60 to 80 points and 80 - 90 points,which had statistically significant differences（P ﹤ 0. 05）. Conclusion：There has a certain value to diagnose coronary heart disease by ECG,but there also exists misdiagnosis. Clinica
