摘　　要：目的比较新西兰兔体表Wilson和头胸(HC)导联假性Q波的分布。方法RM-6000多图像记录仪同步记录两种导联法测定的30只新西兰兔胸背部体表各70点的ECG。根据正常兔假性Q波的出现率和分布范围的差异判断两种导联的诊断价值。结果Wilson导联在胸背部区域都记录到假性Q波,而HC导联仅在背部小范围记录到假性Q波,统计同一测试点两种导联记录到的假性Q波的例数,经χ2检验(P<0.05),有显著性差异。结论HC导联与Wilson导联相比,正常兔的假性Q波出现率低,HC导联出现假性Q波的范围也较Wilson导联局限。Objective To comparetheoccurrenceanddistributionof pseudoQ waveon thebodysurfaceof rabbitsrecorded by Wilsonleadwiththosedetectedby head-chest(HC)lead.Methods ECGswererecordedat eachof the70pointson the thoracodorsalregionsof thebodysurfacein30normalNew-Zealandrabbits.Thediagnosticvalueof the2leadsystemswas assessedon thebasisof thedetectionof occurrenceanddistributionof pseudoQ wave.Results PseudoQ wavewasrecorded at manypointsextensivelyin thethoracodorsalregionsby Wilsonlead,andonlya few testingpointson theupperdorsal surfaceshowedpseudoQ waveactivitywhileby HClead.Atthesametestingpoint,theinstancesof pseudoQ wavedetection by thetwo leadsystemsrespectivelywereshownto be significantlydifferentbyχ 2 test(P<0.05).Conclusion HC leadis superiorto Wilsonleadintermsof itslow occurrencerateandlimiteddistributionregionsof pseudoQ waverecordedon the bodysurfaceof normalrabbits.
