Cardiac electrograms were measured on endocardial leads on patients undergoing pacemaker implantation. The data show that small area electrodes reduce R wave amplitude, decrease width of the complex, and increase slopes. The bandwidth of the electrogram increases as the electrode area decreases. The loading of the sensing amplifier changes these characteristics. Distortion is most pronounced for small area electrodes and low lead resistances.
在接受起搏器植入的患者的心内膜导线上测量心脏电图。数据表明，小面积电极会降低R波幅度，减小复合波宽度，并增加斜率。电图的带宽随着电极面积的减小而增加。传感放大器的负载会改变这些特性。对于小面积电极和低导联电阻，失真最为明显。
