Transvenous Pacemaker Placement: A Review for Emergency Clinicians

Area of Science:

• Emergency Medicine
• Cardiology
• Critical Care

Background:

• Transvenous pacemaker placement is a core skill in emergency medicine for managing severe dysrhythmias.
• Temporary cardiac pacing is a life-saving intervention for various cardiac conditions.

Approach:

• This narrative review focuses on transvenous pacemaker placement specifically within the emergency department.
• Optimal insertion sites include the right internal jugular and left subclavian veins.
• Ultrasound guidance can enhance lead placement accuracy using subxiphoid approaches.

Key Points:

• Indications include symptomatic bradycardia, unstable tachydysrhythmias like torsades de pointes, and failed transcutaneous pacing.
• Successful placement involves advancing a pacing wire with a balloon until electromechanical capture is achieved in the right ventricle.
• Troubleshooting mechanical capture failure requires evaluating equipment and potential malfunctions.

Conclusions:

• A thorough understanding of transvenous pacemaker placement is essential for emergency clinicians.
• Proper technique and awareness of potential complications are crucial for patient safety.
