Baseline wander
Normally, the baseline will stabilize within a few seconds. The following
conditions may also cause an baseline wander:
• Patient breathing
• Dried out or peeling off electrodes
• Improperly prepared skin
• Improperly applied electrodes, with poor skin contact
• Dirty electrodes
• Body motion
Fix the faulty electrode, or turn on the Stable Filter to correct.

Electrical Interference
Electrical interference may produce a wide baseline. Its amplitude depends
on the strength of the current source and the lead being recorded. In any
one lead, the amplitude of the interfering signal is uniform.
