心电图评价小儿过敏性紫癜合并的心肌损害

The electrocardiogram application in pediatric allergic purpura with myocardial damage

目的探究心电图在不同类型小儿过敏性紫癜合并心肌损害的评估、疗效、转归中的指导价值。方法回顾性分析本院82例已确诊过敏性紫癜合并心肌损害患儿的临床资料,住院当日全部行常规12导联心电图检查,以后每周查1次心电图,动态观察心电图变化。结果 82例过敏性紫癜合并心肌损害患儿中63例（76.82%）有心电图改变,63例患儿中混合型紫癜47例（74.60%）,单纯型紫癜5例（7.94%）,其他类型11例（17.46%）;心电图改变呈多样性、易变性;全病程均可出现;心电图改变多数随原发病主要症状消失后1～3w恢复正常,混合型重症病例心电图恢复期需3w以上。混合型紫癜的心电图改变多为2项以上。混合型紫癜心电图改变较重,恢复时间长。结论心电图改变对过敏性紫癜患儿合并心肌损害的评估、疗效、转归具有重要临床意义。

Objective To study the Electrocardiogram guidance value in the assessment, curative effect,outcome of different types of pediatric allergic purpura with myocardial damage. Methods To analyze the clinical data of 82 cases diagnosed HSP with myocardial damage in our hospital. All the cases were checked with 12-lead ECG as soon as they were hospitalized, then to be checked again once a week and to observe the changes of ECG dynamically. Results In 82 cases, 63 of them（76.82%） had abnormal ECG. In 63 cases with ECG changes, 47 of them（74.60%） were hybrid HSP, 5 of them were pure HSP,11 of them were other types of HSP. ECG changes showed multifarious and changeable and they appear in whole course of the disease. Most of the ECG became normal in 1～3weeks after the key primary disease symptoms disappeared. The ECG recovery needed more than 3 weeks in cases with serious Hybrid HSP. ECG changes in cases with hybrid HSP were all more than 2 items, the ECG changes were more serious and the recovery time was longer in cases with hybrid HSP than in cases with the other types.Conclusions Electrocardiogram have important clinical guidance value in the assessment, curative effect, outcome of different types of pediatric allergic purpura with myocardial damage.
