Muscle stimulation related to a nonfunctioning epicardial pacemaker electrode

Area of Science:

• Cardiology
• Biomedical Engineering
• Medical Device Technology

Background:

• Pacemaker leads are crucial for cardiac rhythm management.
• Retained pacemaker leads, especially infected ones, pose complication risks.
• Epicardial electrodes are infrequently used, limiting data on their associated complications.

Observation:

• A case of muscle stimulation was observed.
• The stimulation was linked to a retained epicardial pacemaker electrode.
• This complication arose despite the electrode being noninfected.

Findings:

• Noninfected retained pacemaker leads are associated with fewer complications compared to infected electrodes.
• Complications from retained epicardial electrodes are seldom reported due to their infrequent use.
• Muscle stimulation is a potential complication of retained epicardial pacemaker electrodes.

Implications:

• Highlights the importance of vigilance for rare complications even with noninfected devices.
• Suggests that retained epicardial electrodes, though uncommon, require careful monitoring.
• Underscores the need for reporting and analyzing complications associated with less common medical device placements.
