摘要

对58例心肌梗死后患者的心室复极不均匀性参数与程序性心室刺激结果的相关性进行了评估。猝死高危患者QTc间期持续时间、QT间期和QTa间期离散度根据程序性心室刺激结果与无猝死高危患者相比增加(469.5/spl plusmn/43.2和435.5/spl plusmn/29.6 ms, 60.2/spl plusmn/23.6和43.8/spl plusmn/11.3 ms, 56.71/spl plusmn/27.0和33.7/spl plusmn/14.5 ms,分别)验证了这种无创方法在心肌梗死后患者高危亚群识别中的有效性。

Application of the parameters, reflecting ventricular repolarization inhomogeneity for identification of patients with life-threatening arrhythmias
The correlation between the parameters reflecting ventricular repolarization inhomogeneity and the results of programmed ventricular stimulation was assessed in 58 post-myocardial infarction patients. Registration of increased QTc interval duration and QT and QTa interval dispersion in patients with high risk of sudden death as compared to the patients without it according to the results of programmed ventricular stimulation (469.5/spl plusmn/43.2 and 435.5/spl plusmn/29.6 ms, 60.2/spl plusmn/23.6 and 43.8/spl plusmn/11.3 ms, 56.71/spl plusmn/27.0 and 33.7/spl plusmn/14.5 ms, respectively) demonstrate the efficacy of this non-invasive method in identification of high-risk subgroup of post-myocardial infarction patients.
