摘　　要：目的探讨QT离散度(QTd)在急性颅脑损伤合并脑心综合征患者中预测室性心律失常的临床价值。方法将急性颅脑损伤合并脑心综合征患者50例分为非室性心律失常组39例(A组)和室性心律失常组11例(B组),另选50例健康体检者作为对照组,用12导联同步心电图测量各组的QTd及心率校正后的QTd(QTcd)数值。结果 A组QTd及QTcd与对照组比较,差异无统计学意义(P>0.05);B组较A组和对照组的QTd及QTcd均明显增加,差异均有统计学意义(P<0.05)。结论急性颅脑损伤合并脑心综合征患者发生室性心律失常者QTd及QTcd显著增加,QTd及QTcd可作为预测该类患者发生室性心律失常的一个可靠指标。Objective To investigate the clinical value of QT dispersion（QTd）for predicting ventricular arrhythmia in patients with acute craniocerebral injury complicating cerebrocardiac syn-drome.Methods This study enrolled 100 cases in all.Fifty patients with acute craniocerebral in-jury complicating cerebrocardiac syndrome were divided into non-ventricular arrhythmia group （39 cases,group A）and ventricular arrhythmia group（11 cases,group B）while another 50 healthy people were chosen as control group.QTd and corrective QT dispersion （QTcd）of each group were all measured by 12-lead synchronous ECG.Results Compared with the control group,the differ-ences of QTd and QTcd in group A were neither statistically significant（P〉0.05）.Separately com-pared with group A and control group,QTd and QTcd in group B both significantly increased and the differences were both statistically significant（P 〈0.05）.Conclusion Among patients with a-cute craniocerebral injury complicating cerebrocardiac syndrome,QTd and QTcd significantly in-crease in those accompanied with ventricular arrhythmia and therefore QTd and QTcd can serve as reliable indexes for predicting ventricular arrhythmia in those patients.
