糖尿病微血管病患者QT离散度分析

QT dispersion(QTd) of patients with diabetic microvsclular complication

目的 探讨糖尿病微血管病患者的 QT离散度 (QTd)变化及其意义。方法 分析 5 0例糖尿病并发肾病或 /和视网膜病变患者的体表 12导联同步心电图 ,与 5 2例单纯糖尿病患者及 5 0例正常人作对照。结果 糖尿病肾病或 /和视网膜病变组的 QTd显著高于其余两组 (P <0 .0 0 1)。结论 (1)糖尿病微血管病变可能导致心肌细胞损害影响心室复极 ,从而使 QTd增大 ;(2 )糖尿病患者 QTd增大时 ,可提示微血管病变的发生 ,即

Objective To study the changes of QT dispersion of patients with diabetic microvascular complication and its evaluation Mehods\ To analysis 12 lead synchrony electrocardiograms of 50 patients with diabetic nephropthic or/and ratinopathy those of 52 patients with pure diabetes and those of 50 normal persons were as controls Results\ The QTd with diabetic nephropthic or/and ratinopathy were obviously bigger than those control groups(P<0 01) Conclusion\ (1)The diabetic microvascular complication led to myocardial cell injured,ventricular repolarization was in part prevented so that QTd increased (2)The increase of QTd might imply that diabetic microvascular complication had happened to diabetic patients,so QTd is valuable in detecting certain diabetic microvascular complication \ \
