摘　　要：目的探讨心电图附加导联在诊断右束支传导阻滞（RBBB）中的意义。方法观察450例正常人心电图V1＇、V1＂、V＇＂及V3R导联QRs波形态及演变规律。结果V1＇→V1＂→V＇＂ QRS；R．演变趋势：r波振幅逐渐降低，出现r＇波的概率及r’波振幅逐渐增高，即出现r＇〉r渡概率越来越高。V3R导联无1例出现r波。V1’、V1＂、V1＇＂ LV3R导联出@RBBB图形分别是18例（4％）、105例（23％）、193例（43％）、0例（0％）。结论附加导联作RBBB早期诊断，V1’、V1＂、V1＇＂可能存在假阳性；而V3R导联则未见假阳性，具有较高的可靠性。Objective To investigate the significance of additional leads in diagnosis of right bundle branch block in ECG. Methods 450 cases of normal VI＇, VI＂, VI＇ ＂ and V3R lead QRS waveform morphology and evolution were observed and evaluated. Results V1＇→V1＂→V＇＂ QRS waveform trend is： r wave amplitude decreased, therefore, the probability f waves emergence and amplitude of r＇ wave both increased, ie.the probability ofr＇〉 r wave probability was gradually increasing. In lead V3R, there was no r ＇ wave. Cases of V1＇、V1＂、V1＇＂ and V3R lead that had RBBB graphics were 18 cases （ 4% ） , 105 cases （ 23% ） , 193 cases （ 58% ） , 0 cases （ 0% ） , respectively. Conclusion When using additional leads in early diagnosis ofRBBB, V1＇、V1＂、V1＇＂ may have false positive but V3R did not. Through this study, we can conclude that V3R shows a higher reliability in RBBB early diagnosis.
