[Harmful interference between preoperative prophylactic cardiac pacemaker and cutting diathermy. Case report].

Area of Science:

• Cardiology
• Medical Device Safety
• Electrophysiology

Background:

• Prophylactic cardiac pacing is sometimes used preoperatively.
• Diathermy is a common surgical tool that uses electrical currents.
• The simultaneous use of pacemakers and diathermy presents potential risks.

Observation:

• A patient experienced irreversible ventricular fibrillation during a procedure.
• The event occurred due to the interaction between a prophylactic pacemaker system and cutting diathermy.
• The pacemaker catheter acted as an antenna, capturing electromagnetic currents.

Findings:

• The primary cause identified was the capture of electromagnetic currents by the pacemaker catheter.
• This phenomenon led to a dangerous cardiac event (ventricular fibrillation).
• The study reviews the mechanisms behind such pacemaker-diathermy interactions.

Implications:

• Re-evaluation of indications for prophylactic pacing is necessary.
• Strict safety precautions are crucial when using pacemakers with diathermy.
• This case underscores the importance of understanding electromagnetic interference in medical procedures.
