[摘要] 目的 探讨心电图应用于诊断不典型心肌梗死的价值。方法 比较2016年6月~2017年6月我院接诊的40例不典型心肌梗死患者(观察组)与40例典型心肌梗死患者(对照组)首发症状、心电图特征、心肌酶谱[肌酸激酶(CK)、同工酶(CK-MB)、心肌肌钙蛋白I(cTnI)]检测结果及诊断情况。结果 两组患者首发症状和心电图特征对比,差异有统计学意义(P0.05)。 结论 心电图诊断心肌梗死效果良好,但对于不典型心肌梗死需联合心肌酶谱检测以提高诊断准确率。

[Abstract] Objective To investigate the value of electrocardiogram in the diagnosis of atypical myocardial infarction. Methods The first symptom, electrocardiogram characteristics, the detection results of myocardial enzymes including creatine (CK), isoenzyme (CK-MB) and cardiac troponin I (cTnI) and the diagnosis situation between the 40 patients with atypical myocardial infarction(observation group) and the 40 patients with typical myocardial infarction(control group) in our hospital from June 2016 to June 2017 were compared. Results There were significant differences in the first symptom and electrocardiogram characteristics between the two groups(P0.05). Conclusion ECG has good effect in the diagnosis of myocardial infarction, but for atypical myocardial infarction, myocardial enzyme detection need to be combined with to improve the diagnostic accuracy.

不典型心肌梗死是心肌梗死的常见类型,因其症状不明显,容易造成误诊或漏诊,延误治疗时机[1-2]。优化不典型心肌梗死的诊断技术,提高该病的诊治水平对改善患者预后有重要意义。本研究回顾性分析了我院不典型心肌梗死患者心电图的特征,以期为提高该病诊断准确率提供参考,现报道如下。
1 资料与方法
1.1 一般资料
将2016年6月~2017年6月我院接诊的40例不典型心肌梗死患者纳入观察组。选择同期我院接诊的40例典型心肌梗死患者纳入对照组。观察组男25例,女15例,年龄40~81岁,平均(60.65±6.87)岁,发病时间4~20 h,平均(8.64±1.47)h,合并症:高血压18例,糖尿病16例,高血脂症15例。对照组男26例,女14例,年龄40~82岁,平均(61.07±6.92)岁,发病时间4~20 h,平均(8.58±1.55)h,合并?Y:高血压19例、糖尿病15例、高血脂症16例。两组患者的性别比例、年龄、发病时间及合并症等资料差异无统计学意义(P>0.05),具有可比性。
