目的：探讨跨室壁复极离散度(TDR)预测扩张型心肌病患者室性心律失常(VA)的价值。方法：测定全部156例扩心肌病患者心电图导联TpTe和TpTe/QT的参考值范围,分析其与室性心律失常的关系。结果：扩心肌病患者TpTe和TpTe/QT的参考值范围分别为：69～97ms,0.20～0.24；两者预测室性心律失常敏感度、特异度、阳性预测值、阴性预测值和阳性似然比分别为：48.3%、42.5%、
目的：探討跨室壁複極離散度(TDR)預測擴張型心肌病患者室性心律失常(VA)的價值。方法：測定全部156例擴心肌病患者心電圖導聯TpTe和TpTe/QT的參攷值範圍,分析其與室性心律失常的關繫。結果：擴心肌病患者TpTe和TpTe/QT的參攷值範圍分彆為：69～97ms,0.20～0.24；兩者預測室性心律失常敏感度、特異度、暘性預測值、陰性預測值和暘性似然比分彆為：48.3%、42.5%、

Objective:Discuss the predictive value of transmural dispersion of repolarization (TDR) to incidence of ventricular arrhythmias in patients with dilated cardiomyopathy. Methods:By measuring the reference range of TpTe and TpTe/QT in 156 patients with dilated cardiomyopathy, then analyzing the relationship between ventricular arrhythmias and them. Results:The reference range of TpTe and TpTe/QT in patients with dilated cardiomyopathy are (69~97) ms and (0.20~0.24);Their predictive sensitivity, specificity, positive predictive value, negative predictive value and positive likelihood ratio to ventricular arrhythmias are 48.3%、42.5%, 35.7%, 55.5%, 0.84 and 74.2%, 89.4%, 82.1%, 84.0%, 7. Conclusion:The increase of TDR is an important reason of ventricular arrhythmia, but the predictive value of TpTe to ventricular arrhythmia is smaller than TpTe/QT.
