【摘要】 目的探讨年轻中心型肥胖者的QT离散度(QTd)与ST-T改变的特征。方法对年龄18~35岁的39例单纯性中心型肥胖者与34例正常体重者进行12导心电图记录及测量QTd、QTcd、血压、体重指数(BMI)、腰臀比(WHR)。结果肥胖组收缩压、舒张压为正常高值,QTd、QTcd均大于正常值,与正常组比较差异有统计学意义(P<0.001),且肥胖组出现ST-T改变的病例中QTd增大更明显。结论年轻中心型肥胖者QTd增大,QTd可作为早期预测中心型肥胖者具有高心血管病风险的一项参考指标。更多还原

【Abstract】 Objective To explore the QT dispersion (QTd) and ST-T changes in the central obesity in youth.Methods To measure the electrocardiogram of 12 leads,QTd,QTcd,blood pressure,body mass index(BMI) and waist-hip ratio(WHR) in 39 patients with central obesity(group A) and 34 normal weight healthy control subjects(group B),whose ages ranged from 18 to 35 years.Results The systolic blood pressure and diastolic blood pressure of the group A were higher than normal values,QTd,QTcd in the were group A higher than those in group B(P<0.001).Conclusion QTd in central obesity are higher than the normal reference value.The QTd would be a reference index for forecasting the cardiovascular disease in the central obesity in youth.更多还原
