| 摘 要： | 目的 探讨急性心肌梗塞早期QT离散度的变化与室性。律失常的关系，方法分析60例冠脉正常和58例急性心肌梗塞12导联心电图QTcd。结果急性心梗病人最大QT间期和最大QTC间期与正常对照组差异无显性，而QTd和QTcd明显大于对照组。急性心机梗塞发生室性。律失常的病人明显大于未发生心律失常的病人。结论急性心肌梗塞早期QT离散度增加对预测室性心律失常有一定价值。

| Abstract: | Objective To study the relation of QTc dispersion( QTcd) in acute myocardial infarction (AMI) and Ventricular arrhythmias. Methods QTcd on 12-lead ECG in 58 patients with AMI were measured and comparing with 60 normal ones in the control group. Results The differences of QTmax and QTcmax in AMI were not more obvious than those of the control group,but QTd and QTcd were longer in AMI than those of the control group. QTc and QTcd with Ventricular arrhythmias (VA) in AMI were increased more than those without VA. Conclusion The length of QTd and QTcd in AMI can predict the presence of VA in some sense. |
