摘　　要：目的应用立体心电向量(3D-VCG)技术,对正常人和心肌梗死患者的T波峰-末间期(Tp-Te)及其他复极参数进行对比研究。方法采用3D-VCG技术,分别测量109例心肌梗死和116例正常人的Tp-Te、T环总时间和T环最大振幅参数,比较组间差异性。结果心肌梗死组Tp-Te较正常组显著延长[(114.26±27.54)ms vs(100.40±13.61)ms,P<0.05)],T环总时间两组差异不大[(238.70±40.20)ms vs(241.00±38.25)ms,P>0.05],而心肌梗死组T环最大振幅显著减小[(0.39±0.17)mV vs(0.64±0.23)mV,P<0.001]。结论 3D-VCG显示心肌梗死患者复极参数异常,Tp-Te延长提示其跨室壁复极离散度增加。Objective To compare the Tpeak-tend interval（Tp-Te） and other depolarization data measured by 3-dimension vectrocardiography（3-D VCG） between normal person and myocardial infarction（MI） patients.Methods 3-D VCG technology was adopted,and depolarization data of Tp-Te,total T time and max T volume were collected in 109 patients with MI（MI group） and 116 normal person（normal group）.Data of the two groups were compared statistically.Results Tp-Te was significant longer in the MI group than that in the normal group [（114.26±27.54） ms vs（100.40±13.61） ms,P 0.05];no statistical difference in total T time between the two groups [（238.70±40.20） ms vs（241.00±38.25） ms,P0.05];while max T volume was significant lower in the MI group than that in the normal group [（0.39±0.17） mV vs（0.64±0.23） mV,P 0.001）.Conclusion MI patients present abnormal depolalization indexes in 3-D VCG measurement,longer Tp-Te indicates that transwall depolalization viariation increased.
