摘　　要：目的探讨心电图参比电极电位变化的规律。方法同步比较21例完全性右束支传导阻滞患者头胸导联和常规导联心电图r和R′波变化,分析参比电极电位变化与心室激动方向的关系。结果头胸导联V1r波振幅高于常规导联心电图[(0.16±0.19)vs(0.11±0.13)mV,P<0.01],而其R′波振幅低于常规导联心电图[(0.25±0.21)vs(0.35±0.23)mV,P<0.01]。结论参比点电位变化与心室除极方向变化有关。Objective To explore the rule of voltage change in the reference point of electrocardiograms （ECG）.Methods The r and R＇ waves on the head-chest lead and routine lead ECGs in 21 patients with right bundle branch block in whole synchronization were compared,and the correlation of voltage change in reference point with the direction of cardiac muscular stimulation of ECGs was analyzed.Results The swing of wave r in head-chest leads was significantly higher than that of routine leads （[0.16 ±0.19]vs [0.11 ±0.13]mV,P 0.01）,and the swing of wave R＇ in head-chest leads was significantly lower than that of the routine leads（[0.25 ± 0.21]vs [0.35 ± 0.23]mV,P 0.01）.Conclusion Voltage change in reference point of ECG varies with the direction of cardiac muscular stimulation.
