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.
