摘　　要：目的:探讨年轻肥胖者ST-T改变与Q-T离散度(QTD)。方法:对年龄18岁～35岁的74例单纯性肥胖者(A组)与34例正常体重者(B组)进行12导心电图记录及测量ST-T、QTD、QTCD、血压、体重指数(BMI)、腰臀比(WHR)。结果:A组收缩压、舒张压为正常高值,QTD、QTCD均大于正常值,与B组比较差异有统计学意义(P<0.001),且A组出现ST-T改变的病例中QTD增大更明显。结论:年轻肥胖者出现ST-T改变者,其QTD明显增大,提示两项无创性心电指标(ST-T改变及QTD增大)可作为早期预测年轻肥胖者高心血管病风险的重要参考指标。Objective To explore the relations between the changes of youth obesity ST-T and Q-T dispersion.Methods To conduct the cardiograms and measure ST-T,OTD,OTCD,blood pressure,BMI and WHP for 74 pure obesities （group A） and 34 normal weights （group B） aged from 18-35.Results The result shown that systolic and diastolic pressure for group A were both near the up limit,and QTD and QTCD were over the normal levels,which was statistically significant （P〈0.001） comparing with the data in group B. Besides,the QTD increase was more obvious in those ST-T changes in group A.Conclusion The changes of ST-T of youth obesity always featured with distinct increase of QTD.Thus, these two indicators （the changes of ST-T and the increase of QTD） could be taken as key references when predicting the possibility of angiocardiopathy in youth obesity.
