When a pacemaker is implanted, several electrophysiological parameters are measured using pacing system analyzers (PSA). Different PSAs may use different filter settings and measuring techniques when compared to the implanted pacemaker. In order to determine if there were significant differences in measurements obtained with different PSAs, we obtained measurements in a group of 99 patients with three different PSAs and a manual method. The results show that with each of the three different PSAs tested, different amplitudes of intracardiac electrograms are obtained and that they are usually higher than those obtained by manual measurement of recorded electrograms. Despite significant differences, however, all methods correlate well with each other. Following common practice of pacemaker programming, the use of a PSA for the implantation of a pacemaker that uses different sensing technique does not lead to clinical complications.
植入起搏器时，会使用起搏系统分析仪（PSA）测量多个电生理参数。与植入的起搏器相比，不同的PSA可能会使用不同的滤波设置和测量技术。为了确定使用不同PSA获得的测量结果是否存在显著差异，我们用三种不同的PSA和一种手动方法对99例患者进行了测量。结果表明，在所测试的三种不同PSA中，每种都能获得不同幅度的心内电图，且这些幅度通常高于通过手动测量记录电图所获得的幅度。然而，尽管存在显著差异，但所有方法之间的相关性都很好。按照起搏器程控的常规做法，对于采用不同感知技术的起搏器植入使用PSA不会导致临床并发症。
