目的评估Q-T离散度在判断儿童心肌炎病情中的应用价值;总结正常儿童的Q-T离散度正常值范围。方法采集210例健康儿童、心肌炎患儿及疑似心肌炎儿童的QTd和QTcd值进行统计学分析,并深入探讨心力衰竭、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、心肌炎及疑似心肌炎儿童三组间有明显的差异,且与心肌受损程度呈正相关。②心肌炎患儿中依室性心律失常的有无和心功能不全存在与否进行分组,二组间QTd和QTcd值的差异有显著性。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 value of Q-T dispersion in judging the status of childhood myocarditis and to summarize the range of normal range of Q-T dispersion in normal children. Methods The QTd and QTcd values of 210 healthy children, children with myocarditis and children with myocarditis were collected for statistical analysis. The relationships between heart failure, ventricular arrhythmia and QTd and QTcd were also discussed. Results ①QTd and QTcd values were significantly different among healthy children, myocarditis and children with suspected myocarditis, and were positively correlated with the degree of myocardial damage. ② myocarditis in children according to the presence or absence of ventricular arrhythmia and cardiac insufficiency were grouped, between the two groups QTd and QTcd values were significantly different. Conclusion Q-T dispersion as a noninvasive and simple and convenient detection method has certain reference value in judging the severity of myocarditis and the presence of ventricular arrhythmia and cardiac insufficiency and other serious conditions.
