Summary

Emergency ventricular pacing can be rapidly initiated using a J-configured catheter without fluoroscopy. This technique is reliable, safe, and effective even for inexperienced operators, overcoming common delays in critical care settings.

Area of Science:

  • Cardiology
  • Emergency Medicine
  • Medical Devices

Background:

  • Emergency ventricular pacing is crucial for hemodynamically unstable patients.
  • Delays in pacing initiation are often due to fluoroscopy limitations and operator skill.
  • Existing methods to expedite pacing have proven unreliable or uncomfortable.

Purpose of the Study:

  • To evaluate the efficacy and reliability of a novel J-configured catheter for transvenous ventricular pacing.
  • To assess the feasibility of rapid, fluoroscopy-free pacing in emergency situations.
  • To determine if the technique is effective with operators of limited experience.

Main Methods:

  • A Cordis 5-FG (1.67-mm) "atrial J"-electrode catheter was used for transvenous insertion.
  • Procedures were performed without fluoroscopic guidance in 20 hemodynamically unstable patients.

  • Patient conditions included asystole, high-grade atrioventricular block, and ventricular tachycardia.

    • Main Results:

    • Successful ventricular pacing was achieved in 19 out of 20 patients.
    • Pacing initiation occurred rapidly, with a median time of two minutes from skin puncture.
    • 16 procedures were completed within three minutes, and 15 were performed by operators with less than 10 prior insertions.

    Conclusions:

    • Emergency transvenous ventricular pacing can be initiated quickly and reliably using a J-configured catheter without fluoroscopy.
    • The technique is safe, well-tolerated, and effective even for operators with minimal experience.
    • This method offers a practical solution to overcome common barriers in emergency pacing.
