急性心肌梗死早期QT离散度与预后的关系

Relationship between QT disperse degree and presage consequences in myocardial infarction early-stage

目的研究急性心肌梗死早期QT离散度与预后的关系。方法收集分析46例急性心肌梗死早期患者的QT离散度。结果急性心肌梗死组QT离散度与对照组比较明显延长(P<0.001);急性心肌梗死患者心脏事件组的QT离散度大于急性心肌梗死患者非心脏事件组(P<0.05)。结论QT离散度是急性心肌梗死患者早期发生心脏事件的一项无创伤而有价值的预测指标。

Objective:To investigate the relationship between the QT disperse degree and presage the consequences in early-stage of myocardial infarction.Methods:To collect and analyse QT disperse degree of 46 patients.Results:QT disperse degree of AMI group were long markedly than the comparative(P < 0 001);AMI group of cardiac-event longer than the AMI no-event(P < 0 001).Conclusion:QT disperse degree was a presage ineices of no-wound and great value to AMI early-stage occur mortality of cardiac-event.
