An external, simply operated, fail-safe, automatic pacemaker function analyzer (PFA) has been designed for routine examination of ambulatory patients in local medical clinics and for continual surveillance of hospitalized patients in cardiology units. The instrument provides a comprehensive test of the pacing system, including the battery, pulse generator, and electrodes (leads), during varying heart activity. In the recorded ECG from 92 pacemaker patients, the PFA recognized all but 0.29% of the QRS complexes and 0.21% of the pacing artifacts; no signals were incorrectly attributed to the QRS complex. With the PFA, 1171 pacemaker tests were performed on these patients. In all cases, the PFA judged the performance of the tested pacemakers in accordance with the predetermined criteria. The PFA can be integrated into a pacemaker-patient surveillance system within a general-purpose cardiac care unit.
已设计出一种外部的、操作简单、具有故障安全功能的自动起搏器功能分析仪（PFA），用于当地医疗诊所对门诊患者进行常规检查，以及对心脏病科住院患者进行持续监测。该仪器可在心脏活动变化期间对起搏系统进行全面测试，包括电池、脉冲发生器和电极（导线）。在92例起搏器患者记录的心电图中，PFA识别出了除0.29%的QRS波群和0.21%的起搏伪差之外的所有信号；没有信号被错误地归因于QRS波群。使用PFA对这些患者进行了1171次起搏器测试。在所有情况下，PFA均根据预定标准判断被测起搏器的性能。PFA可集成到通用心脏护理单元内的起搏器患者监测系统中。
