EKG Troubleshooting: Common Artifacts and Their Solutions

Understanding EKG Artifacts

An electrocardiogram (EKG) is a valuable diagnostic tool used in the field of cardiology to assess the electrical activity of the heart. However, there are instances when artifacts, which are unwanted signals or interference, can appear on the EKG strip. These artifacts can distort the interpretation of the EKG and lead to misdiagnosis if not recognized and resolved. In this article, we will explore some common EKG artifacts and their solutions.

EKG Troubleshooting: Common Artifacts and Their Solutions 1

Muscle Noise Artifact

Muscle noise artifact, also known as somatic interference, occurs when there is excessive contractions or movements of the patient’s muscles during the EKG recording. This can arise due to patient movement, shivering, or poor electrode adhesion. To resolve muscle noise artifacts, ensure the patient remains still during the EKG recording. Use adhesive electrodes or tape to secure the electrodes in place and minimize artifact-inducing muscle movements.

60 Hz Interference

60 Hz interference, also referred to as AC interference, is caused by the presence of electrical equipment or power lines in the vicinity of the EKG recording. This interference manifests as a regular sawtooth pattern on the EKG strip. To mitigate 60 Hz interference, ensure that the patient is positioned away from electrical equipment and power sources. Additionally, check the grounding of the EKG machine and its cables to minimize the pickup of external electrical signals.

Baseline Wander

Baseline wander occurs when the baseline of the EKG strip fluctuates or drifts over time. This artifact can result from patient movement, loose electrodes, or poor skin-electrode contact. To address baseline wander, ensure the patient lies as still as possible during the recording. Make sure the electrodes are securely attached to the patient’s skin to maintain proper contact. In some cases, applying electrode gel or saline solution can improve conductivity and reduce baseline drift.

Electrode Motion Artifact

Electrode motion artifact occurs when the electrodes become loose or detached from the patient’s skin during the EKG recording. This can lead to irregular waveforms or erratic spikes on the EKG strip. To prevent electrode motion artifact, ensure that the electrodes are properly secured and making good contact with the skin. Educate the patient about the importance of staying still and avoiding excessive movement during the recording.

Electrical Interference Artifact

Electrical interference artifact can arise from electronic devices, such as smartphones or improperly shielded medical equipment, that emit electromagnetic signals. This interference can manifest as random spikes, sharp deflections, or irregular waveforms on the EKG tracing. To minimize electrical interference artifact, remove or keep electronic devices away from the patient’s vicinity during the EKG recording. Ensure that medical equipment used in the vicinity is properly shielded to prevent electromagnetic interference.

Solution Summary

  • Secure electrodes to minimize muscle noise artifact.
  • Position the patient away from electrical equipment to minimize 60 Hz interference.
  • Minimize patient movement and ensure good electrode contact to reduce baseline wander.
  • Ensure proper electrode adhesion and educate the patient about staying still to prevent electrode motion artifact.
  • Remove electronic devices and ensure proper shielding of medical equipment to minimize electrical interference artifact.
  • By understanding these common EKG artifacts and their corresponding solutions, healthcare professionals can enhance the accuracy of EKG interpretations and make informed clinical decisions. Recognizing and addressing artifacts promptly is essential for reliable EKG analysis and optimal patient care.
