3.4.2 Attaching Electrodes to the Patient
The quality of ECG waveform will be affected by the contact
resistance between the patient and the electrode. In order to get a

Before placing the electrode, make sure that the electrode is clean.
Reusable electrodes should be cleaned immediately after each use.
