Troubleshooting Transvenous Pacemakers with Point of Care Ultrasound (POCUS)

Area of Science:

• Emergency Medicine
• Cardiology
• Medical Ultrasound

Background:

• Unstable bradyarrhythmia necessitates emergent interventions.
• Transvenous pacing (TVP) is a critical, though rarely performed, emergency department procedure.
• Traditional TVP relies on anatomical landmarks, posing challenges for emergency physicians.

Purpose of the Study:

• To describe the utility of point of care ultrasound (POCUS) in emergent transvenous pacemaker (TVP) placement.
• To present a protocol integrating POCUS into standard TVP procedures.
• To highlight POCUS-guided troubleshooting and complication identification during TVP.

Main Methods:

• Review of two clinical cases of emergent TVP.
• Development of a protocol incorporating POCUS for TVP.
• Description of POCUS techniques for vascular access, wire navigation, and complication detection.

Main Results:

• POCUS facilitates initial vascular access for TVP.
• POCUS aids in the precise placement and advancement of the TVP wire.
• POCUS enables rapid identification of potential complications during the procedure.

Conclusions:

• POCUS integration significantly enhances emergent transvenous pacing procedures.
• Emergency physicians can improve TVP success rates and patient safety using POCUS.
• POCUS is an indispensable tool for managing unstable bradyarrhythmia requiring emergent pacing.
