Double sensing by atrial automatic tachycardia-terminating pulse generator.

    Summary

    Double sensing of atrial and QRS signals by an implanted pulse generator caused inappropriate treatment for supraventricular tachycardia. The far-field QRS signal is crucial for accurate tachycardia detection in automatic pulse generators.

    Area of Science:

    • Cardiology
    • Biomedical Engineering
    • Medical Devices

    Background:

    • Supraventricular tachycardia (SVT) is a common arrhythmia requiring therapeutic intervention.
    • Implantable automatic burst tachycardia-terminating pulse generators are used for SVT treatment.
    • Accurate sensing of cardiac signals is critical for device efficacy and patient safety.

    Observation:

    • Two cases of double sensing of atrial (P) and ventricular (QRS) signals were observed.
    • This occurred with an Intermedics CyberTach 60 implanted pulse generator during normal sinus rhythm.
    • The device inappropriately delivered burst stimulation due to sensing at rates slower than programmed detection criteria.

    Findings:

    • The far-field QRS signal interfered with the atrial electrogram sensing.

  • This interference led to misinterpretation of normal sinus rhythm as SVT.
  • Inappropriate burst stimulation was delivered, highlighting a sensing malfunction.

    • Implications:

    • The far-field QRS signal plays a significant role in SVT detection by atrial sensing pulse generators.
    • Device programming and sensing parameters require careful consideration to prevent double sensing.
    • Further research into advanced signal processing algorithms for implantable devices is warranted to improve accuracy and prevent inappropriate therapies.
