目的探讨婴幼儿支气管肺炎心电图P波振幅的特点,为心电图诊断提供科学依据。方法患有支气管肺炎的婴幼儿共143例,分为二组:其中轻症患儿组84例;重症患儿组59例。对照组为同时期门诊查体的正常同龄婴幼儿共96例。对支气管肺炎婴幼儿入院当日、一周PⅡ振幅及一周内心律失常发生率进行比较。结果入院当日PⅡ振幅重症组、轻症组分别较正常组增高,重症组较轻症组增高(P<0.01);入院1周各组间比较,PⅡ振幅重症组较正常组、轻症组增高(P<0.01);二组支气管肺炎患儿入院1周内心律失常比较,重症组较轻症组室上性心律失常发生率增高,差异有统计学意义(P<0.05)。结论婴幼儿支气管肺炎对心电图P波振幅有影响,与病情相关。
Objective To investigate the characteristics of P wave amplitude of bronchopneumonia in infants and young children with electrocardiogram and to provide a scientific basis for ECG diagnosis. Methods A total of 143 infants and young children with bronchopneumonia were divided into two groups: 84 in mild cases and 59 in severe cases. Control group for the same period outpatient examination of normal infants and young children a total of 96 cases. Infants and young children on bronchial pneumonia admission day, week P Ⅱ amplitude and week incidence of arrhythmia were compared. Results On the day of admission, the severity of PⅡ amplitude in severe group and mild disease group were higher than those in normal group, and those in severe group were significantly higher than those in mild group (P <0.01). Compared with normal group and mild group (P <0.01). The incidence of arrhythmia in children with bronchopneumonia within one week after admission was significantly higher in severe group than in mild group (P <0.05). Conclusion Infant bronchopneumonia has an impact on the P wave amplitude of ECG, and is related to the disease.
