Pacemaker erythema, a rare side effect of cardiac devices, presents as skin redness. Physical irritation, not infection or allergy, is the likely cause in patients with pacemakers or defibrillators.

Area of Science:

  • Cardiology
  • Dermatology
  • Medical Device Complications

Background:

  • Pacemaker erythema is a rare, irreversible complication associated with cardiac pacemakers.
  • Clinically, it manifests as localized, telangiectatic erythema (redness) at the device site.
  • Histological examination shows superficial dermal telangiectatic vessels and mild perivascular inflammation.

Observation:

  • This report details three cases of pacemaker erythema occurring after pacemaker or defibrillator implantation.
  • The patients presented with characteristic skin changes around the implanted device.
  • Diagnostic evaluations, including patch testing, were performed to ascertain the cause.

Findings:

  • The exact pathogenesis of pacemaker erythema remains unclear.

  • Histopathology is not specific for this condition.
  • Allergic reactions to implanted materials were excluded based on negative patch test results.

    • Implications:

    • Physical irritation from the implanted cardiac device is a potential triggering factor for pacemaker erythema.
    • Differentiating pacemaker erythema from device-related infections is crucial for appropriate management.
    • Further research is needed to elucidate the underlying mechanisms and develop targeted treatments.
