electrode and to the unit.
Ensure that the ECG electrodes are making good
contact with the patient and are not dried out.
Replace the ECG electrodes.

Noisy ECG, artifact, or wandering
baseline. Turn off nearby two-way radios and cell phones.
Before attaching electrodes, properly prepare the
patient’s skin (refer to “Applying ECG Electrodes” on
page 5-4).
Check for proper adhesion of the electrodes to the
patient.
Arrange the cable and leads so that they do not pull
on the electrodes or swing excessively.
Poor ECG signal level. Replace the ECG electrodes, and change their
position on the patient.
Irregular heart rate. Observe the patient’s ECG. Verify that the irregular
heart rate is not caused by noise, low amplitude
R waves, extra-systoles, or arrhythmias.
Replace the ECG electrodes, and change their
position on the patient.
