摘　　要：目的　研究小儿病毒性心肌炎时QT离散度 (QTd)的动态变化与室性心律失常、心力衰竭等事件发生 ,以及时限性的关系。方法　采用与对照组比较 ,心电图常规 1 2导联、动态心电图 ,计算QTd、QTcd。结果　 (1 )心肌炎组QTd与对照组相比 ,存在显著性差异 (P <0 .0 1 ) ;(2 )心肌炎时QTd变化具有明显的时限性 ,这与心肌炎早期重症并发症发生有密切关系 ;(3)心肌炎QTd与室性心律失常、心力衰竭发生呈正相关。QTd >60ms上述事件发生率明显上升 ,QTd≥ 1 0 0ms其发生率近 1 0 0 %。结论　心肌炎时QTd监测对小儿病毒性心肌炎事件发生的预测有重要价值。Objective\ To evaluate the predictive value of QT in occurance of the viral myocardialitis in infants and venticular arrhythmias.Methods\ Compared with control group in electrocardiograth and motor screening of the ECG.Results\ As for QTd values there was a significant difference between the viral myocardialitis and the control group (P<0.01),and QTd had significant correlations with occurance of the ventricular arrhythmias and the heart failure.Conclusion\ Monitoring of QTd value in infants plays a very important role in the prediction of the occurance of the viral myocardialitis events.
