摘要：
目的: 探讨心电图在小儿过敏性紫癜合并心肌损害中的应用价值。
方法: 在郑州市儿童医院儿科接受治疗的过敏性紫癜合并心肌损害患儿80例，随机分为观察组和对照组各40例。对照组采用常规心电图进行检测。观察组采用动态心电图进行检测。比较两组患儿心电异常检出情况及过敏性紫癜合并心肌损害检查率。
结果: 观察组ST-T改变、QT间期延长、窦性心动过缓、二度窦房传导阻滞窦性检出情况明显高于对照组，差异有统计学意义(P<0.05)|两组心动过速、左室高血压、房性早搏、右束支阻滞、一度房室阻滞、总心电图改变检出情况比较差异无统计学意义(P>0.05)。观察组过敏性紫癜合并心肌损害阳性检出率为97.5%(39/40)，高于对照组72.5%(29/40)，差异有统计学意义(P<0.05)。
结论: 动态心电图能提高小儿过敏性紫癜合并心肌损害的检出率，诊断阳性率较高，能有效判断患儿是否合并心肌损害，可作为临床诊断的重要指标。

Abstract:
Objective: To explore the application value of electrocardiogram in children with allergic purpura complicated with myocardial damage.
Methods: Eighty cases of allergic purpura complicated with myocardial damage treated in Pediatric Department of Children′s Hospital of Zhengzhou City were randomly divided into observation group and control group of 40 cases.Control group was detected by routine ECG.The observation group was detected by dynamic electrocardiogram.The detection rate of abnormal ECG and the rate of myocardial damage in patients with allergic purpura were compared between the two groups.
Results: Rate of ST-T change,prolongation of the QT interval,sinus bradycardia,and degree Ⅱ sinoatrial block was significantly higher in observation group than that of the control group,the difference being statistically significant(P<0.05)|detection rate of tachycardia,left ventricular hypertension,atrial premature beat,right bundle branch block,degree Ⅰ atrioventricular block and the total ECG change had no statistically significant difference(P>0.05).In observation group,the positive rate of myocardial damage was 97.5% (39/40),higher than the control group［72.5%(29/40)］,the difference being statistically significant(P<0.05).
Conclusion: Dynamic electrocardiogram can improve the detection rate of children with allergic purpura and myocardial damage,with higher positive rate of diagnosis,which can effectively determine whether the patients have myocardial damage,so it can be used as an important indicator of clinical diagnosis.
