摘　　要：目的研究血管迷走性晕厥(vasovagal syncope,VVS)患者无症状期间的T波形态学。方法 208例疑诊为VVS患者经直立倾斜试验(head-up tilt test,HUTT)检查分为HUTT阳性组和阴性组,于无症状期间行心电图检查,对两组的T波形态学进行分析研究。结果HUTT阳性组与阴性组的T波MCS[(90.47±40.57)vs.(79.81±33.08)]、Flat-score[(45.73±9.19)vs.(40.40±8.73)]、Tp-Te[(117.83±19.13)ms vs.(111.36±15.86)ms]差异均有统计学意义(P<0.05);Logistic回归分析:Flat-score为HUTT阳性的独立危险因素(OR=1.068,P<0.01);ROC曲线下面积分析:MCS(AUC=0.622,P<0.01),Flat-score(AUC=0.662,P<0.01)。结论 MCS、Flat-score、Tp-Te是HUTT阳性的相关因素,VVS患者无症状期间存在心室复极异常。Objective To study the T-wave morphologic parameters in the patients with vasovagal syncope(VVS).Methods A total of 208 patients suspected with VVS were included in the study.All the cases underwent head-up tilt test(HUTT),and divided into HUTT positive group and HUTT negative group according to testing results.In the absence of any symptom,ECG examination was performed on both of the groups,and T-wave morphologic parameters were analyzed between the two groups.Results Between HUTT positive and negative groups,T-wave morphologic parameters of MCS[(90.47±40.57)vs.(79.81±33.08)],Flat-score[(45.73±9.19)vs.(40.40±8.73)]and Tp-Te[(117.83±19.13)ms vs.(111.36±15.86)ms]were all significantly different(P<0.05).Logistic regression analysis indicated that Flat-score was an independent risk factor for positive HUTT(OR=1.068,P<0.01).Area under the curve(AUC)analysis found that AUC of MCS and Flat-score equalled to 0.622 and 0.662(P<0.01),respectively.Conclusion MCS,Flat-score and Tp-Te were related factors for positive HUTT.Ventricular repolarization abnormality is found in VVS patients during asymptomatic period.
