摘要
目的探讨QT离散度 (QTdispersion ,QTd)在正常人及冠心病患者的意义。 方法观察了 12 0例正常人、14 4例冠心病患者在常规体表同步记录十二导联心电图时的QTd及相关指标。结果正常人的QTd(39.94±12 .13)ms <冠心病组 (5 0 .85± 18.4 4 )ms,冠心病组中有心肌梗死病史者的QTd(5 6 .0 6± 19.30 )ms>无心肌梗死病史的 (48.2 5± 17.5 2 )ms。结论冠心病患者的心室复极不均一性增加 。
ObjectiveTo fully understand the significance of QT dispersion(QTd) in normal controls and patients with coronary heart diseases. Methods120 health controls and 144 patients with coronary heart diseases were studied with routine 12 lead synchronous electrocardiography. QTd and relative indexes were mearsured. ResultsThe results indicated that , QTd in health controls ( 39.94 ± 12.13 )ms is lower than in patients with coronary heart disease ( 50.85 ± 18.44 )ms; QTd in patients with myocardial infarction( 56.06 ± 19.30 )ms is higher than in patients with coronary heart disease, who had no myocardial infarction( 48.25 ± 17.52 )ms.ConclusionIt is concluded that patients with coronary heart disease, especially with myocardial infarction, have higher QTd which means higher different underlying abnormalities of ventricular repolarization.
