    A new Pacemaker Function Analyzer (PFA) offers efficient screening for paced patients, accurately assessing pacemaker (PM) function and battery status. This device simplifies follow-up for both ambulatory and hospitalized patients.

    Area of Science:

    • Biomedical Engineering
    • Cardiology
    • Medical Device Technology

    Background:

    • Pacemaker (PM) function monitoring is crucial for patient management.
    • Existing methods for PM evaluation can be time-consuming and resource-intensive.
    • A need exists for efficient and accurate PM function analysis in clinical practice.

    Purpose of the Study:

    • To introduce and evaluate a semi-automatic external Pacemaker Function Analyzer (PFA) for routine screening of paced patients.
    • To assess the PFA's capability in determining pacemaker battery status, electronic integrity, and electrode function.
    • To explore PFA applications in various clinical settings, including Coronary Care Units (CCU) and specialized pacemaker clinics.

    Main Methods:

    • The PFA analyzes QRS complexes and pacing artifacts for function evaluation.

  • Logic processing of decoded data assesses battery and electronic integrity.
  • Performance was validated on 92 ambulatory and 12 hospitalized patients.

    • Main Results:

    • The PFA demonstrated high accuracy, recognizing 99.71% of QRS complexes and 99.79% of pacing artifacts in ambulatory patients.
    • Simultaneous testing with a physician confirmed identical results for 32 patients.
    • In hospitalized patients, all true PM failures were detected, despite a 5% false-negative alarm rate.

    Conclusions:

    • The PFA is a reliable tool for routine pacemaker function analysis in general practice.
    • It offers potential cost savings and workload reduction for medical staff in managing paced patients.
    • The PFA can be effectively utilized for both ambulatory and hospitalized patient surveillance.
