| 摘要 目的：探讨常规心电图(ECG)与冠脉造影术(CAG)在冠心病诊断中的效果。方法：选取100例冠心病患者，入院后先行CAG，后经ECG检查，通过CAG检查的冠脉狭窄程度、冠脉病变支数与ECG检查结果的对比两种检查方法对冠心病诊断结果，评价ECG与CAG在冠心病诊断中的临床价值。结果：CAG诊断冠心病的阳性诊断率82.0 %，ECG诊断冠心病阳性诊断率为79.0 %，两组阳性诊断率相比，无统计学差异(P>0.05)。ECG对三组冠心病患者的灵敏度分别为65.0%，92.6%，96.9%，冠脉狭窄程度50%-70%时，灵敏度低于其他两组(P<0.05)。经CAG诊断为冠脉单支病变、双支病变、三支病变患者，采用ECG诊断时，组间灵敏度相比，差异有统计学意义(P<0.05)。结论：ECG多支病变冠心病患者容易出现漏诊、误诊情况，CAG与ECG诊断灵敏度相当，可直观反映冠脉病变情况。 |

| ABSTRACT Objective: To discuss the efficacy of ECG and CAG in the diagnosis of coronary heart disease. Methods: Selecting 100 cases of coronary heart disease patients. They were given CAG first, then ECG. The efficacy of ECG and CAG in the diagnosis of coro- nary heart disease was evaluated by diagnosis of coronary heart disease, degree of coronary artery stenosis, the number of coronary artery lesions by CAG. Results: The diagnosis rate of coronary artery stenosis was 82.0% by CAG and 79.0% by ECG. There were no statistical significance on diagnosis rate between two groups(P>0.05). From results, the sensitivity was 65.0%, 92.6% and 96.9% in 3 groups. When the degree of coronary artery stenosis was 50%-70%, the sensitivity was lower than that of other two groups (P<0.05). The coronary artery stenosis was diagnosed as single vessel disease, double vessel disease and three vessel disease. When using ECG, the sensitivity had no statistical difference among groups(P>0.05). Conclusion: ECG had high sensitivity on coronary artery stenosis. The detection was convenient and noninvasive. But the misdiagnosis was still exsited. The CAG had equal sensitivity with ECG. It could reflect the situa- tion of coronary lesions directly. But the examination was limited because of traumatic. |
