ECG loose lead effect

If a lead becomes loose, you can get baseline wander

TO REDUCE BASELINE WANDER: A) Use muscle relaxation B) Arrange patient cable so there is no pull on the lead wires to prevent electrodes from moving C) Check for secure application of electrodes. Loose electrodes may accentuate wandering caused by movement of the limbs D) Discourage excess movement during the test E) Wipe the skin with alcohol. Shave if necessary.
