What causes wondering base line in ekg?

Wandering baseline in an EKG is primarily caused by movement or shifting of the electrodes, which may occur due to patient movement, breathing, or poor electrode placement. It can also result from changes in skin impedance or electrical interference from other devices. This fluctuating baseline can obscure the true cardiac signals, making it difficult to accurately interpret the EKG. Proper electrode placement and minimizing patient movement can help mitigate this issue.
