摘　　要：目的:观察起搏前后心电图参比点电位的变化及其规律。方法:同步记录永久性起搏器植入术患者右室起搏与非起搏时头胸导联和常规导联2种心电图,比较Q波、R波和S波振幅。结果:非起搏时,常规导联Q波、S波振幅大于头胸导联,常规导联R波振幅小于头胸导联;起搏时,常规导联心电图Q波、R波、S波振幅均小于头胸导联(P均<0.01)。结论:心电活动的传导方向对参比点的电位变化有较大影响。Objective：To study the changes and rules of the reference point potentials of electrocardiograms （ECGs） before and after pacing. Methods： The head-chest lead and routine lead ECGs of the patients with permanent pacemaker implantation were recorded with and without right ventricular pacing; the Q, R and S wave amplitudes were compared between the 2 ECGs. Results： Without right ventricular pacing, the amplitudes of Q and S wave of routine lead were higher than those of the headchest lead; the amplitude of R wave was lower than that of the head-chest lead. With right ventricle pacing, the amplitudes of Q, R, and S waves of routine lead were lower than those of head-chest lead（all P〈0. 01）. Conclusion： The transduction direction of the cardiac excitement has great influence on the potentials of the reference point.
