摘要 目的探讨冠心病患者QT离散度(QTd)与其室性早搏Lown's分级的关系。方法前瞻性、顺序地观察了60例冠心病患者动态心电图室性早搏Lown's级别与同日测量QTd及相关指标的变化。结果室早Lown's4~5级冠心病患者QTd、QTcd、QTmax显著大于0级和1~3级患者(分别101±39.4vs62±22.9、60±23.4,115±53.7vs68±25.9、70±21.6和463±57.8vs430±41.4、422±29.3均P<0.05),而QTmin无显著改变(P>0.05)。而室早Lown's0级与1~3级患者比较则QTd及相关指标均无显著差异(P>0.05)。结论室早Lown's4~5级冠心病患者QTd显著增大。 Objective To understand the relationship between Lown's stratification of ventricular ectopic and QT dispersion in patients with coronary artery disease.Methods Prospective investigate the QTd (QT dispersion)、QTcd (Corrected QT dispersion)、QTmax(Maximal QT interval)、QTmin(Minimal QT interval) and Lown's stratification of ventricular ectopic in dynamic electrocardiogram of sixty patients.Results Compared with Lown's 0 or 1~3 stratification patients,the QTd、QTcd and QTmax of Lown's 4~5 stratification patients with coronary artery disease were increased significantly(101±39.4vs62±22.9、60±23.4,115±53.7vs68±25.9、70±21.6 and 463±57.8vs430±41.4、422±29.3 all P <0.05),but the QTmin were no changed ( P >0.05),There was no-significant difference in QTd、QTcd、QTmax and QTmin between Lown's 0 stratification patients and Lown's 1~3 ( P >0.05). Conclusion The QT dispersion is increased and increase risk for ventricular reentrant tachycardia in Lown's 4~5 stratification patients with coronary artery disease.
