摘　　要：目的　探讨围产期心肌病 (PPCM)心电图QT、JT间期离散度 (QTd、JTd)与心律失常及死亡的关系。方法　测量并计算 34例PPCM体表心电图QTd、JTd ,并将 36例无器质性心脏病的孕产妇作为对照组。结果　PPCM恶性心律失常组QTd、JTd较无恶性心律失常组及对照组显著增加 (P <0 .0 1) ;无恶性心律失常组QTd、JTd较对照组亦显著增加 (P <0 .0 1) ;PPCM死亡组较生存组QTd、JTd亦明显增加 (P <0 .0 1)。结论　QTd、JTd增加是预测PPCM发生恶性心律失常及死亡的重要指标之一。Objectives To investigate the change of QTd、JTd、arrhythmia and death.Methods The QTd、JTd in surface electrocardiologrphy of 34 patients of PPCM were measured and compard to those of 36 pregnants without heart disease.Results The QTd、JTd in petients with PPCM were markly increased than those of controls(P<0.01).The QTd、JTd in patients with maligmant arrhythmia group were significantly increased than those of the group without maligmant arrhythmia(P<0.01).The QTd、JTd of dead patients were also significantly increased than those of patients(P<0.01).Conclusions The increase of QTd、JTd was an important index indicating the occurence of maligmant arrhythmia and death in patients with PPCM.
