What does the term 'wandering baseline' refer to in an EKG tracing?

The term 'wandering baseline' in an EKG tracing refers to inconsistencies in the trace that are often caused by poor electrode connections or movement. When the baseline of the EKG fluctuates rather than remaining stable, it can lead to difficulty in interpreting the heart's electrical activity accurately. This phenomenon can arise from various factors, including improper placement of electrodes, changes in the patient's position, or interference from external sources.

Understanding that a wandering baseline signifies a compromise in the quality of the EKG recording is crucial for healthcare professionals, as it can lead to misinterpretation of the underlying cardiac rhythms. Maintaining proper electrode placement and ensuring that the EKG equipment is functioning correctly are key steps in mitigating this issue during monitoring.
