早期复极综合征与急性心肌梗死QT间期离散度的对比分析

Contrasting analysis of early repolurization syndrome between QT dispersion of acute myocardial infarction

目的探讨早期复极综合征与急性心肌梗死ST段抬高、QT间期、QT离散度(QTd)之间的关系。方法测定早期复极综合征(32例)和急性心肌梗死(32例)患者的心电图,以校正的QTd为指标作对比分析。结果QT离散度早期复极综合征为(43.43±13.26)ms,急性心肌梗死为(69.7±30)ms,两组比较有显著差异(P<0.01)。结论对比QTd具有无创、简便易行的优点,可作为早期复极综合征与急性心肌梗死鉴别的一项有效指标。

Objective To explore relationship of early repolurization syndrome between ST segment rising and QT interval and QT-dispersion(QTd) of acute myocardial infarction.Methods To measure early repolurization syndrome electrocardiogram(32cases) and emendated QTd of acute myocardial infarction(32cases),and contrasting analysis is made.Results QTd and early repolurization syndrome are(43.43±13.26)ms.Acute myocardial infarction is(69.7±30)ms.Contrast two groups is significantly different(P<0.01).Conclusion It has no-wound and simple and convenient feasible merit to contrasting analysis QTd.Moreover,It may be an efficiency index of distinguishing early repolurization syndrome and acute myocardial infarction.
