Pacemaker Failure to Capture Caused by Electrocautery: A Rare Pacemaker Pulse Generator Change Complication.

Area of Science:

• Cardiology
• Biomedical Engineering
• Medical Device Technology

Background:

• Cardiac device implantation and replacement are common procedures.
• Electrocautery (EC) is frequently used for hemostasis during these procedures.
• Device manufacturers provide varying recommendations regarding EC use.

Observation:

• A case of dual-chamber cardiac device pulse generator change is presented.
• Electrocautery use during the procedure led to a sudden, unexpected loss of pacing function.
• The pacing dysfunction persisted for approximately 30 seconds.

Findings:

• Electrocautery can transiently impair cardiac pacing device function.
• This event occurred despite electrocautery generally being considered safe for device procedures.
• The specific mechanism of electrocautery-induced pacing failure in this instance warrants further investigation.

Implications:

• Highlights potential risks of electrocautery during cardiac device generator changes.
• Suggests a need for standardized protocols and heightened awareness when using electrocautery near implanted cardiac devices.
• Underscores the importance of evaluating procedural safety in high-risk device interventions.
