How to Troubleshoot EKG Tracing Artifacts Like a Pro!

What is a troubleshoot?

When this type of tracing is seen, what action should the EKG technician take?

Answer:

A troubleshoot refers to the process of identifying and resolving issues or problems in a system, device, or equipment.

When an EKG technician encounters tracing artifacts, such as baseline wander, powerline interference, somatic tremor, or incomplete baseline artifact, it is crucial to troubleshoot and address these issues promptly to ensure accurate readings and diagnosis.

Baseline Wander:

A low-frequency noise of about 0.5 to 0.6 Hz called baseline wander can occur in EKG tracings. To eliminate baseline wander, the EKG technician should apply a high-pass filter with a cut-off frequency of 0.5 to 0.6 Hz.

Powerline Interference:

To address powerline interference, which is noise from the mains supply at 50 or 60 Hz, the technician can use a notch filter with a cut-off frequency of 50 or 60 Hz to eliminate this interference.

Somatic Tremor:

Patient movement, such as shivering or chewing gum, can cause somatic tremor artifact in EKG tracings. The technician can help reduce somatic tremor by providing a warm blanket to the patient if they are feeling cold or frightened.

Incomplete Baseline Artifact:

Incomplete baseline artifact can be caused by patient cable breaks where the metal tip of the lead wire separates from the alligator clip. To correct this, the technician should change the patient cable or securely fasten the metal lead wire tip to the alligator clip.
