| Wandering Baseline |
Generally caused by one or more of the following:
- Insufficient skin preparation
- Patient moving during recording
- Poor application
- Tense Patient
|
| Solution: |
| Assuming good skin preparation and electrode application, allow a short time for the electrodes to stabilize then repeat the recording. Arm lead hook-ups should be as close to the shoulder as possible. Very tense patients should be instructed to sit on their hands with palms facing down. |
