ECG : Baseline wander is a non cardiac signal problem in recording the ecg.

Don't worry: Nothing to worry about. Baseline wander on the ECG means that the straight line in between the spikes and waves is not so straight! it can wiggle up and down due to electrical interference, a problem with the electrical lead or pad, or oil/lotion/hair on the chest which can interfere with the electrical conduction.
