8. POSITIONING THE ELECTRODES
WARNING: Connect the patient to the SpiderView only when the back of the SpiderView is
in place.
Electrodes supplied with SpiderView have been designed to withstand long-term ambulatory
recording while ensuring patient comfort. Nevertheless, other ECG electrodes may be used.
To ensure a good quality ECG recording, special care must be taken when preparing the
patient’s skin, positioning the electrodes and connecting the leads. Clean the patient’s skin
with soapy solution, cleanse it and dry the skin to reduce impedance and obtain a good
electrode-skin contact.
Electrodes must be firmly attached to avoid air bubbles which could impede proper contact.
A loop should be made in each lead and the lead then attached with adhesive strips close to
the electrode. Pressure on an electrode could produce artifacts.
The proposed electrode placements are an example. It is essential to ensure that the QRS
complex amplitude is sufficient in at least one lead, to make automatic data analysis possible.
The user can verify electrode placement using the ECG preview.

WARNING: Conductive parts of electrodes (including the neutral electrode), should not be
put in contact with conductive parts or grounded parts.
