Abstract
Background
The Abbott Aveir single-chamber pacemaker utilizes thermal rate modulation to adapt pacing rates based on changes in central venous temperature, simulating physiological responses to exercise. However, this feature may lead to unintended tachycardia in critically ill patients, particularly during hemodialysis.
Objective
To describe a case of inappropriate tachycardia induced by the Abbott Aveir pacemaker’s thermal rate modulation feature during hemodialysis and to emphasize the need for careful programming in vulnerable patient populations.
Methods
A single case report was analyzed, focusing on a 38-year-old male with methamphetamine-induced cardiomyopathy and chronotropic incompetence who underwent Abbott Aveir pacemaker implantation. Clinical course, device settings, and outcomes were reviewed to assess the impact of thermal rate modulation.
Results
Following pacemaker implantation, the patient required hemodialysis due to progressive renal failure. Within 5 minutes of hemodialysis initiation, the pacemaker’s thermal rate modulation feature detected a drop in central venous temperature, triggering pacing at the upper rate limit of 130 bpm. This response exacerbated the patient’s hemodynamic instability. Deactivation of thermal rate modulation resolved the issue, underscoring its role in the adverse event.
Conclusion
Thermal rate modulation in the Abbott Aveir pacemaker can cause inappropriate high pacing rates during hemodialysis, posing risks for critically ill patients. Tailored device programming is crucial to prevent iatrogenic complications in such cases.
