摘要
目的:评估Q-T离散度在儿童心肌炎病情中的应用价值。方法:采集46例心肌炎患儿,84例健康儿童的QTd和QTcd值进行统计学分析,并探讨心力衰竭、室性心律失常存在情况及心功能指标与QTd和QTcd值间的关系。结果:①QTd和QTcd值在健康儿童、心肌炎患儿间的差异有统计学意义,且与心肌受损程度呈正相关。②心肌炎患儿中对室性心律失常的有无和心功能不全存在与否进行分组,亚组间QTd和QTcd值的差异有统计学意义。结论:Q-T离散度作为一个无创且简便易行的检测方法,在判断心肌炎的严重程度以及是否存在室性心律失常和心功能不全等严重状况有一定的参考意义。
Objective：To evaluate the of Q-T dispersion in clinical assessment of pediatric myocarditis. Methods：The QTd and QTcd value were taken in totally 96 cases including healthy children, patients with myocarditis. They were analysed in Ventricular arrhythmia and heart failure. Results ： ① Significant difference was found between of the two groups and the value of QTd and QTcd was correlated with the severity of heart disease. ②The children with myocarditis were divided into two subgroups based on the occurrence of ventricular arrhythmia and cardiac failure. There were significant differences between the two subgroups. Conclusions：As an uninvasive clinical method, Q-T dispersion can be used as a measure to assess the severity of myocarditis and the presence of the emergent situations such as ventricular arrhythmia or cardiac failure.
