Malfunctioning American Pacemaker Company (APC) Devices pacemakers caused dangerous rate increases in two patients with sick sinus syndrome. Caution is advised when using these specific APC pacemaker models due to potential design flaws.

Area of Science:

  • Cardiology
  • Biomedical Engineering
  • Medical Device Safety

Background:

  • Sick sinus syndrome requires pacemaker implantation for rate regulation.
  • American Pacemaker Company (APC) Devices pacemakers are used for temporary pacing.
  • Models EC 4542 and EV 4543 were utilized in the reported cases.

Observation:

  • Two patients experienced unexpected, significant increases in pacemaker pacing rates.
  • The pacing rate increases were transient but substantial (53% and 83% above preset rates).
  • These events occurred during temporary pacing for sick sinus syndrome.

Findings:

  • The observed rate increases exceeded the expected rate during electrical interference.
  • The pacemaker's automatic adjustment to interference may have malfunctioned.

  • Potential design flaws in APC Devices models EC 4542 and EV 4543 are suggested.

    • Implications:

    • This suggests a potential safety risk associated with specific APC Devices pacemaker models.
    • Healthcare providers should exercise extreme caution when using these devices.
    • Further investigation into the pacing rate regulation mechanism of these pacemakers is warranted.
