动态心电图与常规心电图在冠心病患者心律失常中的诊断比较

Comparison of dynamic ECG and routine ECG in diagnosis of coronary heart disease patients with arrhythmia

目的:比较两种心电图对冠心病患者心律失常的诊断价值。方法:选取142例冠心病患者,分别采用动态与常规心电图进行监测,比较其诊断结果。结果:常规心电图诊断阳性患者37例,阳性率52.11%;动态心电图组诊断阳性患者48例,阴性患者23例,阳性率67.01%,两种方法阳性率上无统计学意义(P>0.05)。动态心电图检出冠心病患者室性早搏二三联律、房性早搏成对、室性早搏成对及短阵室上速有效率较常规心电图更高(P<0.05)。对室性早搏早发、房室传导阻滞等诊断率无统计学差异(P>0.05)。结论:动态心电图诊断冠心病心律失常患者的灵敏度与有效率高于常规心电图,具有较高应用价值。

Objective:To compare values of two kinds of ECG in diagnosis of coronary heart disease patients with arrhythmia. Methods:142 cases with coronary heart disease were monitored with dynamic electrocardiogram ( ECG) and routine ECG, respective-ly. The diagnosis results of the two groups were compared. Results:37 cases were positive in routine ECG diagnosis, and the positive rate was 52. 11%;while 48 cases were positive and 23 cases were negative in the dynamic ECG, the positive rate was 67. 01%, and there was no statistically significant in the positive rate between the two methods (P>0. 05). The effective rates for diagnosing bigeminy or trigeminy of ventricular premature beats, paired atrial and ventricular premature beats, and paroxysmal supraventricular tachycardia of dynamic ECG were much higher than those of routine ECG(P<0. 05). There were no statistical differences in the diagnosis of ven-tricular premature beats and atrioventricular block between the two methods (P>0. 05). Conclusions:Dynamic ECG in the diagnosis of coronary heart disease and arrhythmia has superior sensitivity and effective rate than routine ECG, and has a high popularization val-ue.
