Continuous veno-venous hemodialysis can cause electrocardiographic artifacts that mimic atrial flutter. Physicians must recognize these artifacts to avoid misdiagnosis in patients with end-stage renal disease.

Area of Science:

  • Cardiology
  • Nephrology
  • Biomedical Engineering

Background:

  • End-stage renal disease (ESRD) is frequently associated with cardiac complications, including atrial tachyarrhythmias.
  • Hemodialysis is a common treatment for ESRD, but its interaction with cardiac monitoring requires careful consideration.

Observation:

  • A case is presented where electrocardiographic (ECG) monitoring during continuous veno-venous hemodialysis (CVVH) revealed an artifact.
  • This artifact closely simulated the pattern of atrial flutter on the ECG.

Findings:

  • The observed ECG artifact was directly attributable to the CVVH equipment.
  • The artifact mimicked atrial flutter, posing a potential diagnostic challenge.

Implications:

  • Clinicians managing patients on CVVH must be vigilant for ECG artifacts.
  • Distinguishing true atrial tachyarrhythmias from dialysis-induced artifacts is crucial for appropriate patient management and avoiding unnecessary interventions.
