摘　　要：对35例扩张型心肌病（DCM）患者入院心电图的QT间期离散度（QTd）及JT问期离散度（JTd）进行了测定。结果：DCM持续性室速及／或原发性室颤（VT／Vf）患者QTd及JTd均显著高于无VT／Vf组（QTd86．30±24．70ms，41．20±10.60ms，P＜0．01。JTd83．50±26．30ms，38．50±12．40ms．P＜0．01）。提示：QTd或JTd增大．VT／Vf发生可能性增大。认为；QTd及／或JTd可作为评估DCM近期预后的重要参考指标。The authors have meaured QT dispersion (QTd)and JT dispersion (JTd)of electrocardiograms of 35 patients with dilated cardiomyopathy (DCM). The resultsshow that the QTd and JTd in 11 patients with persistent ventricular tachycardia and/orventricular fibrilation (VT/VF) are significantly higher than those without VT/VF(QTd 86. 30±24. 70ms,41. 20±10. 60ms, P<0. 01;JTd83. 50±26. 30ms,38. 50±12.40ms, P<0, 01). This results suggest that the increasing of QTd and/or JTd may bepossibly related to the happening of VT/VF in DCM. Thus, we conslder that the QTdand/or JTd have significant prediction value in the judgement of prognosis of DCM in.
