| 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106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(Ⅰ组)QTd、QTcd、QTc、QTcd/QTc与无心脏事件发生组(Ⅱ组)比较有显著的统计学差异(P<0.05、<0.01、<0.05、<0.001)。结论QTd、QTcd、QTc、QTcd/QTc是心衰病人心脏事件独立预测因子，QTcd/QTc准确性最高。 |

| Abstract: | Objective:To investigate the predictive value of QT interval dispersion (QTd),cor rected QT interval dispersion (QTcd) and corrected QT interval(QTc) of car diac 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 predictin g cardiac events of CHF patients. In which,QTcd/QTc is the most accurate factor. |
