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.
