Which condition on an EKG results in a movement-related baseline shift?

The condition that results in a movement-related baseline shift on an EKG is the wandering baseline. This phenomenon typically occurs due to various factors, such as patient movement, loose electrodes, or variations in breathing. When patients move or shift during the EKG recording, it can create a fluctuating baseline, making it difficult to interpret the actual cardiac activity.

In a wandering baseline, the entire waveform gradually shifts up and down from the centerline, which can obscure the analysis of the PQRST complex that is critical for diagnosing cardiac conditions. Proper electrode placement and ensuring patient calmness during the procedure can help mitigate this issue.

This understanding is crucial for medical assistants when preparing patients for EKGs, as minimizing movement and ensuring leads are correctly applied can help achieve clearer readings.
