What could cause an interrupted baseline in an EKG tracing?

  1. Patient movement

  2. Lead corrosion or dirty leads

  3. Normal electrode placement

  4. Electrolyte imbalance

The correct answer is: Lead corrosion or dirty leads

An interrupted baseline in an EKG tracing is primarily caused by issues related to the integrity of the electrodes and leads used during the test. When the leads are corroded or dirty, it can create interference in the electrical signals being transmitted from the heart to the EKG machine. This interference disrupts the baseline, leading to erratic or irregular readings. Maintaining clean, well-functioning leads is crucial for obtaining an accurate EKG. If the leads are not in proper condition, they can contribute to artifacts and variations in the baseline, making it difficult to interpret the heart's electrical activity correctly. Therefore, ensuring lead cleanliness and proper connection is essential for clear EKG results.
