对比分析高频心电图与常规心电图诊断隐匿型冠心病的结果

Comparative analysis diagnosis of coronary heart disease and latent coronary heart disease by high frequency electrocardiogram(HFECG) and conventional electrocardiogram(ECG)

目的:对比高频心电图与常规心电图在隐匿性冠心病临床诊断中的应用价值。方法:选取隐匿性冠心病患者100例,作为研究对象。所有患者均经选择性冠脉造影确诊,采用随机数表法将其分为观察组与对照组,每组50例,其中对照组患者单纯进行常规心电图检查,观察组在对照组基础上进行高频心电图复查,根据两组患者心电图表现进行诊断,比较两组检查方案的敏感度与准确性。结果:观察组检查确诊为隐匿性心脏病48例,准确率为96.00%,敏感度为94.00%,观察组诊断敏感度与准确率明显高于对照组,差异具有统计学意义(P<0.05)。结论:常规心电图在诊断隐匿性冠心病中存在诸多不足,而高频心电图对隐匿性冠心病具有更高的准确性,临床可用于对隐匿性心脏病疑似病例的确诊复查手段。

Objective To contrast application value of diagnosis of coronary heart disease and latent coronary heart disease by high frequency electrocardiogram（ HFECG） and conventional electrocardiogram（ ECG）. Method 100 cases with latent coronary heart disease were selected as the research object. All patients were confirmed by selective coronary angiography and divided into the observation group and control group,50 cases in each group according to stochastic indicator. Control group patients with simple routine ECG examination,observation group based on the control group added high frequency electrocardiogram（ ECG） review,according to two groups of patients＇ electrocardiogram diagnosis,the sensitivity and accuracy of inspection had been compared. Results There were 48 cases diagnosed latent coronary heart disease. The accuracy was 96. 00% and the sensitivity was 94. 00%,the diagnostic sensitivity and accuracy of observation group was obviously higher than that of control group,the difference was statistically significant（ P〈0. 05）. Conclusion There some shortcomings for conventional electrocardiogram（ ECG）in diagnosing latent coronary heart disease,while high frequency electrocardiogram（ ECG） for latent coronary heart disease has higher accuracy,and can be used to clinical suspected cases review diagnosis of the latent coronary heart disease.
