What type of electrical artifact can appear on a 12 lead EKG?

The presence of 60 cycle interference on a 12-lead EKG is primarily due to electromagnetic interference from electrical equipment that operates at a frequency of 60 Hertz, which is common in many countries, including the United States. This type of artifact manifests as rhythmic interference on the EKG tracing, resembling a sine wave pattern, and can often obscure the underlying cardiac electrical activity, leading to potential misinterpretation of the EKG.

Recognizing this artifact is crucial, as it can mimic other cardiac conditions, making it important for healthcare providers to differentiate between true cardiac signals and interference. Identifying and addressing this form of artifact can enhance the accuracy of EKG readings and ensure appropriate patient care.
