摘　　要：目的 :探讨 QT离散度 (QTd)、校正 QT离散度 (QTcd)及心率校正 QT间期 (QTc)对心衰患者心脏事件的预测价值。方法 :回顾性研究了 10 6例充血性心力衰竭 (CHF)患者 QTd、 QTcd、及 QTc的资料。结果 :心脏事件发生组 CHF病人 ( 组 ) QTd、QTcd、QTc、QTcd/ QTc与无心脏事件发生组 ( 组 )比较有显著的统计学差异(P<0 .0 5、 <0 .0 1、 <0 .0 5、 <0 .0 0 1)。结论 :QTd、QTcd、QTc、QTcd/ QTc是心衰病人心脏事件独立预测因子 ,QTcd/Objective:To investigate the predictive value of QT interval dispersion (QTd),corrected QT interval dispersion (QTcd) and corrected QT interval(QTc) of cardiac events in patients with congestive heart failure (CHF).Methods:QTd、QTcd、QTc and QTcd/QTc of 106 CHF patients were reviewed.Results:QTd、QTcd、QTc and QTcd/QTc of patients with and without cardiac events had significant difference respectively( P <0 05、<0 01、<0 05、<0 001 respectively).Conclusion:QTd、QTcd、QTc and QTcd/QTc are independent factors in predicting cardiac events of CHF patients. In which,QTcd/QTc is the most accurate factor.
