What is the primary issue that can lead to a poor tracing on a 12 lead EKG?

The primary issue that can lead to a poor tracing on a 12-lead EKG is patient movement. When a patient moves during the recording of the EKG, it can cause artifacts—irregularities that distort the heart's electrical signals—leading to an inaccurate representation of the cardiac rhythm and function. These artifacts can make it difficult to interpret the EKG readings accurately, which is crucial for diagnosing any underlying cardiac conditions.

While factors like vehicle movement, poor skin preparation, and body hair can contribute to suboptimal EKG quality, the impact of a patient's movement is generally the most immediate and significant concern during the recording process. Ensuring that the patient remains still and comfortable is vital for obtaining a clear and reliable tracing, which aids healthcare providers in accurate diagnosis and treatment planning.
