871例新生儿肺炎心电图异常检出率的分析及临床意义

Clinical significance of detection rate of abnormal ECG:analysis on ECGs of 871 neonates with pneumonia

目的探讨新生儿肺炎心电图异常检出率的临床实际意义。方法选取2014年1月至2015年5月我院收治的871例新生儿肺炎患者为研究对象,根据其病情严重程度,分为轻症肺炎组(785例)和重症肺炎组(86例);并以同期100例正常足月新生儿作为健康对照组,比较三组新生儿的心电图情况。结果重症肺炎组及轻症肺炎组心电图异常发生率显著高于健康对照组,其中重症肺炎组心电图异常发生率明显高于轻症肺炎组,差异有统计学意义(P<0.05);重症肺炎组及轻症肺炎组心电图异常合并情况发生率显著高于健康对照组,其中重症肺炎组心电图异常合并情况发生率明显高于轻症肺炎组,差异有统计学意义(P<0.05)。结论新生儿肺炎患者存在多种类型心电图异常。心肌受到损害,心电图就可能出现异常,并与其心肌受损程度相关。常规心电图改变对疾病的诊断、治疗和预后评价具有重要的应用价值。

Objective To explore the clinical significance of detection rate of abnormal electro-cardiogram（ECG）of neonates with pneumonia.Methods A total of 871 cases with neonatal pneu-monia were selected as research objects who had been admitted by our hospital from January 201 4 to May 201 5.They were divided into mild pneumonia group（785 cases）and severe pneumonia group （86 cases）according to its severity while another 1 00 healthy newborns in the same period were taken as healthy control group.ECGs were compared among the three groups.Results The inci-dence of abnormal ECG in severe pneumonia group and mild pneumonia group was significantly higher than that in health control group and the rate in severe pneumonia group was also significantly higher if compared with mild pneumonia group,both with statistically significant differences（P 〈0.05）.In severe pneumonia group and mild pneumonia group,the incidences of complications of ECG abnormalities were significantly higher if compared with health control group and the incidences in severe pneumonia group were also significantly higher than those in mild pneumonia group,both with statistically significant differences（P 〈0.05）.Conclusion Various types of ECG abnormali-ties can be found in neonates with pneumonia.Myocardial damage is associated with the presence of ECG abnormalities which are related to the degree of myocardial lesions.Therefore,routine ECG changes have important practical value in diagnosing,treating and making prognosis evaluation of diseases.
